HOW is this done??? How CLOSE DO YOU HAVE TO BE??? Could this have been AIMED AT TRUMP???
It is good for several hundred yards...
THEY could be OUTSIDE your HOUSE right NOW!
It is an aimed and concentrated microwave oven pointed at your face that can fry your face and eyes in a few seconds. It is like looking at the sun directly for several minutes. But almost instant sunburn at the same time.
Unfortunately, this is a very easy thing to create. The inner cavity of the eyeball has a certain size. I do not remember the frequency but it is in the sub megahertz band. Used to work with in car police radios and if you were to close to the antenna, radios with certain frequencies they will give you eye irritation. Directional antenna and the right frequency could definitely cause eye injury. But also very easy to detect and locate since the power needed is fairly high. Probably over 50 watts.
The Thing, also known as the Great Seal bug, was one of the first covert listening devices (or "bugs") to use passive techniques to transmit an audio signal. It was concealed inside a gift given by the Soviet Union to W. Averell Harriman, the United States Ambassador to the Soviet Union, on August 4, 1945.https://en.wikipedia.org/wiki/The_Thing_(listening_device)
The Thing consisted of a tiny capacitive membrane connected to a small quarter-wavelength antenna; it had no power supply or active electronic components. The device, a passive cavity resonator, became active only when a radio signal of the correct frequency was sent to the device from an external transmitter. This is referred to in NSA parlance as "illuminating" a passive device. Sound waves (from voices inside the ambassador's office) passed through the thin wood case, striking the membrane and causing it to vibrate. The movement of the membrane varied the capacitance "seen" by the antenna, which in turn modulated the radio waves that struck and were re-transmitted by the Thing. A receiver demodulated the signal so that sound picked up by the microphone could be heard, just as an ordinary radio receiver demodulates radio signals and outputs sound.Its design made the listening device very difficult to detect, because it was very small, had no power supply or active electronic components, and did not radiate any signal unless it was actively being irradiated remotely. These same design features, along with the overall simplicity of the device, made it very reliable and gave it a potentially unlimited operational life.
The device consisted of a 9-inch-long (23 cm) monopole antenna (quarter-wave for 330 megahertz [MHz] frequencies, but it was also able to act as half-wave [at 660 MHz] or full-wave [at 1320 MHz]; the accounts differ. Given the radio technology of the time, the frequency of 330 MHz is most likely, equivalent to a wavelength of 91 cm).[4]
Microwaves are a type of electromagnetic radiation that have a frequency range of 300 megahertz (MHz) to 300 gigahertz (GHz).
Remember how Microwaves cook food in the kitchen.
The article is saying that the same sort of device that was used to "illuminate" or "energize" the Great Seal Bug was pointed at the crowd at President's rally.
