Microwave weapons are supposed to be a type of direct energy weapon. Direct-energy weapons damage their target with highly focused energy including laser, sonic, and microwaves are one such type of weapons. They use beams of high-frequency electromagnetic radiation to heat the water in a human target’s skin which causes pain and discomfort. The microwaves agitate the water molecules in the food and their vibration produces heat that cooks the food. A number of countries are thought to have developed these weapons to target both humans and electronic systems. India has also made a breakthrough in its efforts to develop directed energy weapons or DEWs that will soon put it firmly in control of its own fate. DRDO has conducted a successful test of a laser system. These types of directed energy microwave devices came on the scene in the late 1960s in the US and the Soviet Union. They were enabled by the development of pulsed power in the 1960s. Pulsed power generates short electrical pulses that have very high electrical power, meaning both high voltage – up to a few megavolts – and large electrical currents – tens of kiloamps. That is more voltage than the highest-voltage long-distance power transmission lines, and about the amount of current in a lightning bolt. The US apparently deployed such a weapon in Afghanistan but withdrew it without ever using it against human targets. China had first put on display its “microwave weapon” called Poly WB -1 at an air show in 2014. High-power microwaves impact people through the Frey effect. The human head acts as a receiving antenna for microwaves in the low gigahertz frequency range. Pulses of microwaves in these frequencies can cause people to hear sounds. Other symptoms (Havana syndrome) include headaches, nausea, hearing loss, lightheadedness, and cognitive issues. Havana Syndrome: The mystery ailment that has afflicted the United States embassy staff and Central Intelligence Agency officers off and on over the last four years in Cuba, China, Russia and other countries appears to have been caused by high-power microwaves, according to a report released by the National Academies. A committee of 19 experts in medicine and other fields concluded that directed, pulsed radiofrequency energy is the “most plausible mechanism” to explain the illness, dubbed Havana syndrome. 1 Reply Share Share Share on Facebook Share on Twitter Share on WhatsApp Cancel the best answer Leave an answerCancel replyYou must login or register to add a new answer.
