【The New York Times】Microwave Weapons Are Prime Suspect in Ills of U.S. Embassy Workers
Sept. 1, 2018

More recently, the American military itself sought to develop microwave arms that could invisibly beam painfully loud booms and even spoken words into people’s heads. The aims were to disable attackers and wage psychological warfare.
Now, doctors and scientists say such unconventional weapons may have caused the baffling symptoms and ailments that, starting in late 2016, hit more than three dozen American diplomats and family members in Cuba and China. The Cuban incidents resulted in a diplomatic rupture between Havana and Washington.

In particular, a growing number of analysts cite an eerie phenomenon known as the Frey effect, named after Allan H. Frey, an American scientist. Long ago, he found that microwaves can trick the brain into perceiving what seem to be ordinary sounds.
Hearing Microwaves
Scientists have known for decades that the brain can perceive some microwaves as sound.
MICROWAVES hitting the head in the area around the temporal lobe were perceived as sound in a 1962 experiment. Several theories have sought to explain the exact mechanism but it remains in dispute.
SOUND WAVES entering the ear make the eardrum vibrate. These vibrations are conveyed to the cochlea and converted into electrical signals. The brain’s temporal lobes receive signals from the ears and process them into sounds and speech.
The false sensations, the experts say, may account for a defining symptom of the diplomatic incidents — the perception of loud noises, including ringing, buzzing and grinding. Initially, experts cited those symptoms as evidence of stealthy attacks with sonic weapons.

The dimensions of the human head, scientists say, make it a fairly good antenna for picking up microwave signals.
Mr. Frey, a biologist, said he stumbled on the acoustic effect in 1960 while working for General Electric’s Advanced Electronics Center at Cornell University. A man who measured radar signals at a nearby G.E. facility came up to him at a meeting and confided that he could hear the beam’s pulses — zip, zip, zip.
Intrigued, Mr. Frey traveled to the man’s workplace in Syracuse and positioned himself in a radar beam. “Lo,” he recalled, “I could hear it, too.”
Mr. Frey’s resulting papers — reporting that even deaf people could hear the false sounds — founded a new field of study on radiation’s neural impacts. Mr. Frey’s first paper, in 1961, reported that power densities 160 times lower than “the standard maximum safe level for continuous ********（此词在本论坛发不出来）” could induce the sonic delusions.
His second paper, in 1962, pinpointed the brain’s receptor site as the temporal lobes, which extend beneath the temples. Each lobe bears a small region — the auditory cortex — that processes nerve signals from the outer and inner ears.
Investigators raced to confirm and extend Mr. Frey’s findings. At first they named the phenomenon after him, but eventually called it the microwave auditory effect and, in time, more generally, radio-frequency hearing.
The Soviets took notice. Not long after his initial discoveries, Mr. Frey said, he was invited by the Soviet Academy of Sciences to visit and lecture. Toward the end, in a surprise, he was taken outside Moscow to a military base surrounded by armed guards and barbed-wire fences.
“They had me visiting the various labs and discussing the problems,” including the neural impacts of microwaves, Mr. Frey recalled. “I got an inside look at their classified program.”
Moscow was so intrigued by the prospect of mind control that it adopted a special terminology for the overall class of envisioned arms, calling them psychophysical and psychotronic.
Soviet research on microwaves for “internal sound perception,” the Defense Intelligence Agency warned in 1976, showed great promise for “disrupting the behavior patterns of military or diplomatic personnel.”
Furtively, globally, the threat grew.
The National Security Agency gave Mark S. Zaid, a Washington lawyer who routinely gets security clearances to discuss classified matters, a statement on how a foreign power built a weapon “designed to bathe a target’s living quarters in microwaves, causing numerous physical effects, including a damaged nervous system.”
Mr. Zaid said a N.S.A. client of his who traveled there watched in disbelief as his nervous system later unraveled, starting with control of his fingers.
Washington, too, foresaw new kinds of arms.
In Albuquerque, N.M., Air Force scientists sought to beam comprehensible speech into the heads of adversaries. Their novel approach won a patent in 2002, and an update in 2003. Both were assigned to the Air Force secretary, helping limit the idea’s dissemination.
The lead inventor said the research team had “experimentally demonstrated” that the “signal is intelligible.” As for the invention’s uses, an Air Force disclosure form listed the first application as “Psychological Warfare.”
The Navy sought to paralyze. The Frey effect was to induce sounds powerful enough to cause painful discomfort and, if needed, leave targets unable to move. The weapon, the Navy noted, would have a “low probability of fatalities or permanent injuries.”
In a twist, the 2003 contract was awarded to microwave experts who had emigrated to the United States from Russia and Ukraine.
It is unknown if Washington deploys such arms. But the Pentagon built a related weapon known as the Active Denial System, hailing it in a video. It fires an invisible beam meant to deter mobs and attackers with fiery sensations.
Russia, China and many European states are seen as having the know-how to make basic microwave weapons that can debilitate, sow noise or even kill. Advanced powers, experts say, might accomplish more nuanced aims such as beaming spoken words into people’s heads. Only intelligence agencies know which nations actually possess and use such unfamiliar arms.
