METHOD AND DEVICE OF MICROWAVE ELECTROMAGNETIC IMPACT AT TRESPASSER Russian patent published in 2014 - IPC G08B13/181 

FIELD: electricity.

SUBSTANCE: group of inventions relates to the field of production of mechanical vibrations with the help of electromagnetism and may be used in systems of physical protection of objects from trespassers. The method of microwave electromagnetic impact at a trespasser suggests using an amplitude-modulated microwave electromagnetic field with variable modulation frequency. At the same time frequencies of amplitude modulation are taken in the range of mechanical resonant frequencies of a trespasser's head and separate elements of its acoustic organ, providing for non-lethal pain stimulation. The device of microwave electromagnetic impact at a trespasser comprises a microwave generator with an emitting antenna, an amplitude modulator and a unit of low frequency tuning, made as capable of tuning for mechanical resonant frequency of a trespasser's head and separate elements of its acoustic organs. At the same time the outlet of the low frequency tuning unit is connected to a control input of an amplitude modulator, the output of which is connected to a control input of the microwave generator.

EFFECT: reduced energy inputs and eliminated possibility to injure a person.
