Directed Energy Weapons
Directed Energy Weapons (commonly abbreviated as DEWs) are a class of weapons systems that deliver highly focused energy — in the form of electromagnetic radiation, lasers, microwaves, particle beams, or sonic waves — to a target at or near the speed of light. Unlike conventional kinetic weapons that rely on explosive force or physical projectiles, DEWs transfer energy directly into a target, producing effects that can range from surface heating and disorientation to deep tissue damage, neurological disruption, and death. Their ability to operate invisibly, silently, and at range makes them uniquely suited to both overt military applications and covert operations against individuals.
While DEWs are sometimes discussed as emerging or theoretical technology, a substantial body of declassified research, military procurement records, and public demonstrations confirms that directed energy systems have been operationally developed since at least the mid-20th century. The relevance of DEWs to the Targeted Individuals community is significant: many reported symptoms experienced by TIs — burning sensations, internal vibrations, sudden pain, cognitive disruption, and organ stress — are consistent with known DEW effects, and the emergence of Havana Syndrome as a formally acknowledged phenomenon has lent considerable institutional credibility to these claims.
DEWs occupy a central position within the broader taxonomy of Non-Lethal Weapons and Behavioral Effects Weapons. Academic literature published through Springer and other defence science outlets classifies directed energy systems — particularly microwave and acoustic weapons — as core instruments within the Behavioral Effects Weapons (BEW) framework, which encompasses weapons specifically designed to influence, manipulate, or incapacitate human cognition, perception, and behaviour rather than to kill outright. This classification is significant: it acknowledges that the primary design intent of many DEW systems is not physical destruction but psychological and neurological control.
The development of directed energy weapons does not occur in a strategic vacuum. The doctrine of Full Spectrum Dominance — formally articulated in US Joint Vision 2020 and embedded in Pentagon planning since the 1990s — frames the electromagnetic spectrum itself as a domain of warfare to be controlled, contested, and exploited. Under this doctrine, DEWs are not merely tactical tools but instruments of electromagnetic spectrum dominance: means by which a technologically superior force can achieve decisive advantage across all physical and informational domains simultaneously. This strategic framing explains the sustained investment in DEW research across generations of military and intelligence programs, and contextualises the use of directed energy technologies not only on conventional battlefields but in the grey zones of covert operations, population management, and information warfare.
Categories of Directed Energy Weapons
Microwave and Radiofrequency Weapons
Microwave-based DEWs operate by directing concentrated radiofrequency (RF) or microwave energy at a target. At lower power levels, these systems can induce heating, discomfort, and disorientation. At higher power levels or with sustained exposure, they are capable of causing deep tissue damage, internal burns, and potentially lethal cardiac or neurological effects.
A foundational technology underpinning many microwave DEW systems is the Maser (Microwave Amplification by Stimulated Emission of Radiation) — the microwave-frequency counterpart to the optical laser. Masers produce highly coherent, focused beams of microwave-frequency electromagnetic radiation and form the physical basis for a number of high-powered directed energy systems used in both research and weapons applications. Just as lasers amplify light through stimulated emission, masers perform the equivalent function in the microwave spectrum, enabling the generation of intense, directional microwave beams capable of penetrating materials and interacting with biological tissue at depth. Military-grade maser technology represents a significant advance over broad-spectrum RF emitters, allowing precise targeting with minimal environmental scatter.
The best-documented publicly acknowledged microwave DEW is the Active Denial System (ADS), developed by the US Air Force Research Laboratory and Raytheon. The ADS uses a 95 GHz millimetre-wave beam to heat the water molecules in the skin's surface to approximately 54°C, producing an intense burning sensation that compels subjects to flee. It has been described as a non-lethal crowd control tool, though critics note that the distinction between non-lethal and lethal is largely a matter of power level and exposure duration. The ADS is among the most publicly visible applications of Millimeter Wave Technology in a weapons context.
At lower, less perceptible power levels, microwave systems — including those based on Maser principles — are associated with the Microwave Auditory Effect — the basis of Voice to Skull technology — and with bioeffects on the nervous system, immune function, and hormonal regulation that have been studied extensively in both Western and Soviet research programs. Barry Trower, a former British military microwave weapons specialist, has been particularly vocal about the biological harm caused by pulsed microwave radiation at sub-thermal power levels, drawing on his background in Royal Navy microwave weapons research to argue that many reported neurological effects in civilian populations are consistent with deliberate or incidental microwave exposure.
Signal Modulation and CHIRP Technology
The effectiveness of directed energy systems — particularly pulsed microwave and radar-integrated targeting platforms — depends critically on the modulation schemes used to encode, focus, and deliver energy. CHIRP Technology (Compressed High-Intensity Radar Pulse, also known as chirp spread spectrum modulation) is a signal modulation technique in which the carrier frequency is swept linearly across a defined bandwidth over the pulse duration, producing a characteristic frequency-swept waveform.
Originally developed for radar applications to achieve high range resolution without requiring extremely short pulse durations, CHIRP modulation has significant relevance to pulsed directed energy systems for several reasons:
- Enhanced penetration and focusing — chirped waveforms can be compressed on reception or interaction, delivering high instantaneous power density at the point of focus while reducing the average power required during transmission. This improves the signal-to-noise characteristics of targeting systems and allows more precise energy deposition in biological tissue.
- Radar and targeting integration — modern DEW platforms are typically integrated with radar or lidar targeting systems that use CHIRP-derived waveforms for target acquisition and tracking. The same modulation infrastructure used for radar ranging can be adapted for energy delivery, creating dual-function sensor-weapon platforms consistent with Full Spectrum Dominance doctrine.
- Bioeffect specificity — some researchers have proposed that chirped or frequency-swept pulsed emissions may interact with biological tissue differently from single-frequency continuous-wave or simple pulsed signals, potentially enabling more targeted neurological or physiological effects at lower average power levels. This remains an area of active, if largely classified, investigation.
CHIRP modulation is therefore relevant both to the technical operation of advanced DEW platforms and to the broader question of how pulsed directed energy signals are structured for covert biological effect — a question of direct relevance to the Neuroweapons field and to TI testimony describing pulsed, intermittent, or frequency-varying symptom onset.
Millimeter Wave Weapons
Millimeter Wave Technology refers to electromagnetic radiation in the 30–300 GHz frequency band, with corresponding wavelengths of 1–10 millimetres. This band sits between conventional microwave frequencies and the terahertz (THz) spectrum, and its physical properties make it particularly effective for directed energy weapons applications: millimetre waves penetrate air with relatively low atmospheric loss, interact strongly with biological tissue — particularly the skin and superficial neural structures — and can be focused into precise beams using compact antenna arrays.
The weapons applications of millimetre waves span several distinct categories:
- Skin heating and pain induction — at frequencies around 94–95 GHz, millimetre waves are absorbed almost entirely within the top 1–2 mm of skin, rapidly heating surface tissue to pain-inducing temperatures. This is the operating principle of the Active Denial System, which the US military has deployed as a crowd-control deterrent. The system can engage targets at ranges exceeding 700 metres, providing standoff capability without conventional ballistic risk.
- Covert individual targeting — intelligence community researchers and independent analysts have raised the possibility that lower-power, more precisely focused millimetre-wave systems could be used for covert harassment of individuals. At sub-threshold power levels, such systems could induce biological effects — sleep disruption, skin sensations, neurological irritation — without crossing into immediately perceptible heating, making attribution and detection difficult.
- Penetration and scanning — millimetre waves penetrate clothing and some building materials, a property exploited in security scanning systems (airport body scanners) and, according to some researchers, in systems allegedly used to surveil and target individuals through walls. This penetration characteristic distinguishes millimetre wave systems from optical lasers and gives them particular relevance to Electronic Harassment reports in which targets describe symptoms occurring indoors, through solid structures.
- Neurological coupling — some researchers have proposed that at specific frequency ranges within the millimetre wave band, resonance effects with neural tissue or implanted nanoscale materials could amplify biological impact significantly beyond what is predicted by simple thermal modelling. This remains a contested area, but is consistent with the broader body of Bioelectromagnetics research on non-thermal RF bioeffects.
The CIA has conducted internal assessments of millimetre-wave weapons technology, including their potential for use in both offensive and defensive applications. Declassified documentation confirms agency-level interest in the weapons potential of the millimetre-wave spectrum going back several decades — a primary source document is available at .
For a detailed technical treatment of this frequency band and its applications in surveillance, weapons, and bioeffects research, see the dedicated article: Millimeter Wave Technology.
Laser and High-Energy Optical Weapons
High-energy laser (HEL) weapons concentrate photonic energy into a narrow beam capable of burning, blinding, or destroying targets. Military applications include missile defence, drone interdiction, and vehicle disablement. The US Navy's Laser Weapon System (LaWS) and Lockheed Martin's HELIOS system represent publicly confirmed operational deployments.
At lower power levels, laser-based systems can be used for temporary or permanent blinding — effects that have been reported by some Targeted Individuals and journalists operating in sensitive environments. The use of directed laser devices against protesters and journalists has been documented in multiple countries.
Sonic and Acoustic Weapons

Acoustic DEWs use highly focused sound waves — including both audible and infrasonic or ultrasonic frequencies — to produce effects ranging from disorientation and nausea to pain, incapacitation, and potential internal injury. The Long Range Acoustic Device (LRAD) is a publicly acknowledged system used by military and law enforcement for crowd control and communication.
More controversially, infrasonic weapons operating below the threshold of human hearing are reported to produce profound psychological effects including panic, disorientation, visual disturbances, and a pervasive sense of dread. Some researchers link infrasonic exposure to poltergeist-like experiences and anomalous perception phenomena. The alleged use of infrasonic systems against individuals in their homes is a recurring theme in Electronic Harassment testimony.
Particle Beam Weapons
Particle beam weapons accelerate charged or neutral particles to high velocity and direct them at a target. They have been a focus of military research since at least the 1970s, including under the DARPA-linked Strategic Defense Initiative (SDI). While large-scale operational deployment of particle beam weapons remains classified or unconfirmed, directed neutron beam research has been documented in both US and Soviet military science literature.
Scalar and Longitudinal Wave Systems
Some researchers, including those working in the tradition of Nikola Tesla's later experimental work, describe a further category of directed energy systems operating via scalar waves or longitudinal electromagnetic waves — modes of energy propagation not recognised in mainstream physics but reportedly weaponised in classified programs. According to researchers such as Robert Duncan, scalar-based systems may underpin some of the more anomalous effects reported by Targeted Individuals, including effects that appear to penetrate conventional electromagnetic shielding. These claims remain in the domain of disputed and emerging research.
Documented History of Development
Cold War Research
Both the United States and the Soviet Union pursued directed energy research extensively during the Cold War. The Soviet program, sometimes referred to under the umbrella of psychotronic weapons research, investigated the biological and neurological effects of microwave and RF radiation on human subjects. Declassified US intelligence assessments from the 1970s expressed concern about the Soviet development of microwave-based systems — potentially including Maser-derived technologies — capable of affecting human cognition and behaviour at a distance.
In the United States, the Pandora Project — a classified research effort begun in the 1960s — investigated the biological effects of microwave radiation on the brain and nervous system, partly in response to the discovery that Soviet intelligence had been irradiating the US Embassy in Moscow with microwave signals. This became known as the Moscow Signal incident and represents one of the earliest documented cases of suspected covert DEW deployment against a civilian and diplomatic population.
DARPA and Advanced Research Programs
DARPA has funded extensive research into directed energy systems across multiple decades, including programs relating to high-energy lasers, high-power microwave systems, and neurological effects of RF exposure. Some DARPA-funded research intersects with Remote Neural Monitoring and neuroweapons development, including work on transcranial electromagnetic stimulation and the brain-machine interface technologies documented under programs such as N3 (Next-Generation Non-Surgical Neurotechnology).
A particularly important dimension of DARPA's directed energy work is its intersection with human performance research. The DARPA Human Enhancement Programmes — encompassing initiatives in cognitive augmentation, neural interfacing, and biological resilience — represent the dual-use face of the same research infrastructure that produces weapons-grade directed energy systems. Technologies developed to enhance soldier cognition and performance under electromagnetic stress are functionally related to those designed to degrade adversary cognition through directed energy exposure; the distinction lies in the direction of application rather than the underlying science. This dual-use character is a recurring theme in the broader critique of military neuroscience and forms a central concern within the Neuroweapons literature.
James Giordano, a neuroscientist at Georgetown University who has served on DARPA advisory panels, has spoken publicly about the weaponisation of neuroscience and the capacity of directed energy systems — including those derived from Maser and high-power microwave technologies, as well as emerging millimetre-wave platforms — to disrupt, degrade, or manipulate neural function at ranges and power levels that would not be detectable by the target. Giordano has specifically noted that the convergence of directed energy, neuropharmacology, and nanotechnology creates weapons capabilities that exceed current international legal frameworks.
Full Spectrum Dominance and Strategic Context
The doctrine of Full Spectrum Dominance provides the overarching strategic rationale for sustained investment in directed energy weapons. Articulated formally in the US Joint Chiefs of Staff document Joint Vision 2020 (2000), Full Spectrum Dominance describes the goal of achieving decisive military superiority across land, sea, air, space, and the information environment simultaneously. Within this framework, the electromagnetic spectrum is both a domain of conflict and a medium of weapons delivery.
DEWs are uniquely suited to Full Spectrum Dominance objectives because they operate across multiple domains simultaneously: a directed energy system can serve as a sensor (radar/lidar), a communications platform, and a weapons delivery mechanism within the same hardware architecture. The integration of CHIRP modulation into radar-weapon hybrid platforms exemplifies this multi-domain convergence. Under Full Spectrum Dominance doctrine, such systems are not merely weapons but nodes in an integrated electromagnetic battlespace management architecture.
Critically, Full Spectrum Dominance doctrine does not restrict its scope to conventional military adversaries. The doctrine explicitly includes the ability to shape and control the information environment and to deny adversaries — broadly defined — the ability to operate effectively in any domain. This expansive definition provides a strategic rationale for the application of directed energy technologies in domestic contexts, against non-state actors, and in the grey zones of psychological and information operations — precisely the contexts most relevant to Targeted Individuals and Electronic Harassment research.
Millimeter Wave Intelligence Assessments
The CIA's interest in the offensive potential of millimetre-wave energy extends beyond public acknowledgement of systems like the Active Denial System. Declassified internal assessments — including the document available at — reveal that intelligence analysts were tracking the development of millimetre-wave technologies by both US laboratories and foreign state actors, evaluating their potential for use in denial, disruption, and covert targeting operations. These assessments predate the public rollout of the ADS by several years, suggesting that weapons-grade applications of Millimeter Wave Technology were being developed in parallel with, and likely in advance of, what has been publicly disclosed.
Patents and Technical Literature
A significant body of patent literature confirms the development of DEW technologies that overlap with TI-reported experiences. Notable examples include:
- US Patent 3,951,134 — a method for influencing the nervous system using pulsed RF fields
- US Patent 6,470,214 — a device for producing sound within the skull using microwave signals (directly relevant to Voice to Skull)
- US Patent 5,159,703 — a silent subliminal presentation system using frequency modulation
- US Patent 6,017,302 — acoustic heterodyne systems for projecting sound into a subject's skull
These patents, filed by researchers and defence contractors, demonstrate that the technical foundations of reported TI experiences exist not merely as theory but as formally registered intellectual property.
Havana Syndrome and Official Acknowledgement
The most significant recent development in the official acknowledgement of covert DEW use is the Havana Syndrome episode. Beginning in 2016, US diplomats and CIA officers stationed in Havana, Cuba began reporting sudden-onset neurological symptoms: intense pressure in the head, piercing directional sounds, cognitive impairment, memory loss, and balance disorders. Similar reports subsequently emerged from US personnel in China, Russia, Austria, and elsewhere.
A 2020 report by the National Academies of Sciences concluded that directed pulsed radiofrequency energy was the most plausible explanation for the reported symptoms — effectively confirming, at the institutional level, that covert directed energy attacks on individuals are not only theoretically possible but appear to have occurred. The frequency characteristics described in the NAS report are consistent with pulsed millimetre-wave or high-GHz microwave emissions — precisely the range covered by Millimeter Wave Technology and systems such as the Active Denial System. Researchers have noted that Maser-class devices capable of generating coherent, directed pulsed microwave energy would be consistent with the weapon profile suggested by the NAS report. The CIA subsequently acknowledged that an adversarial nation-state actor was the likely source, though formal attribution has not been made public.
For the Targeted Individuals community, Havana Syndrome represents a pivotal moment of institutional validation. TIs have reported symptom clusters virtually identical to those experienced by Havana Syndrome victims for decades — the primary distinction being that diplomats and intelligence officers are considered credible witnesses, while civilian TIs have historically been dismissed.
DEWs and the Targeted Individuals Phenomenon
Within the TI community, DEWs are widely identified as the primary mechanism of physical harassment and biological harm. Commonly reported effects consistent with DEW exposure include:
- Burning or heating sensations on the skin or internally, often at night
- Sudden sharp pain in specific body regions without contact
- Heart palpitations and cardiovascular stress
- Sleep disruption, often attributed to pulsed microwave or sonic systems
- Tinnitus, clicking, and other auditory intrusions (see Voice to Skull and Microwave Auditory Effect)
- Neurological effects including cognitive fog, forced thought loops, and emotional disruption (see Remote Neural Monitoring)
- Eye and visual system effects
- Apparent targeting of internal organs, particularly kidneys and liver
Some researchers suggest that DEW systems used against TIs may be mounted on vehicles, aircraft (including drones), satellites, or installed in neighbouring properties or infrastructure — a contention that aligns with TI reports of symptoms varying with location and time of day. The penetration characteristics of Millimeter Wave Technology — which can pass through clothing and certain building materials — make millimetre-wave platforms particularly relevant to reports of targeting through walls and ceilings.
The integration of Nanotechnology and bio-integrated materials is a developing area of concern. Some researchers, including Ana Mihalcea, have proposed that nanoscale materials potentially present in the body — whether introduced via chemtrails, vaccines, or other environmental vectors — may serve as internal antenna or receiver systems that enhance the effectiveness of external DEW targeting, making individuals more susceptible to remote influence at lower power levels. In this model, even relatively low-power Maser or microwave beam systems could achieve significant biological effects by coupling with nano-scale internal receivers already present within the target's body.
Countermeasures and Detection
TIs and independent researchers have explored various approaches to detecting and mitigating DEW exposure:
- RF and microwave detection meters — consumer-grade devices capable of detecting anomalous electromagnetic fields in the environment
- Faraday shielding — conductive enclosures or garments intended to attenuate incoming electromagnetic signals
- Shielded sleeping areas — the construction of shielded canopies or rooms to reduce nocturnal exposure
- Biometric monitoring — continuous logging of physiological parameters to document anomalous events
Detection of millimetre-wave emissions in particular requires specialised equipment operating in the 30–300 GHz band; standard consumer RF meters often do not cover this range, meaning that Millimeter Wave Technology-based targeting may go entirely undetected by individuals relying on off-the-shelf detection equipment. Similarly, CHIRP-modulated pulsed signals — by virtue of their frequency-swept, spread-spectrum character — may evade simple threshold detection systems designed to trigger on narrowband or continuous-wave emissions, presenting additional challenges for TIs attempting to document directed energy exposure with consumer instrumentation.
The efficacy of these countermeasures is debated within the TI community, with some reporting partial relief and others finding no benefit — a pattern consistent with either the variability of targeting systems or the involvement of mechanisms, such as implanted nano-receivers, that operate from within the body rather than relying solely on external energy delivery.
