Abstract

A device for damaging electronic equipment has a millimeter wave generator, such as a gyrotron oscillator, for producing very high power millimeter waves. A beam former antenna forms the millimeter waves into narrow beams for distance transmission. An antenna coupled to the gyrotron directs narrow beams of the millimeter waves to selected targets, whereby the beams damage electronic equipment at the targets. The millimeter wave generator produces frequencies ranging from about 100 to 140 GHz at 20 millisecond megawatt pulses at 400 kilowatts CW.
