Study of Damage Mechanism of High Power Microwave on Electronic Equipments

Abstract

Currently, damage effect of high power microwave 2. HPM characteristics analysis (HPM) on electronic equipments is of increasing interest. HPM can disturb, damage, or destroy many military or civilThere are several parameters, such as frequency, pulse electronic equipments. In this paper, the representative HPM width, pulse rise and fall times, pulse repetition rate, and waveform iS investigated in time and frequency field with pus rieadfl.ie,plerptto ae n waveorm s inestiatedin ime nd fequecy feld power level, which can affect the characteristics of HPM.respectively, and the main characteristics (peak power, rise HPwe vel, w ana affect the canracter cs ofi HM time, power density, etc) are analyzed and listed. HPM HPM waveform analysis in time and frequency field iS generation devices and radiation are also discussed. Coupling presented respectively in this section. energy into electronic devices via front door and back door, as a function of coupling coefficient and the effective area, is 2.1 HPMwaveform modeled. By presenting lots of kinds of coupling modes and Fig. 1 illustrates a representative HPM waveform. As can paths, damage effects are divided into five different classes, be seen from the figure, the HPM waveform has very and damage mechanism of HPM on electronic equipments is fast rising time, slow falling time and short pulse proven in the paper.duration. The frequency band of HPM is narrow, not like
