With the microelectronization of the modern electronic systems, the electronic systems are more vulnerable to electromagnetic pulse(EMP) especially after the appearing of high power microwave(HPM) and E-bomb.

• 随着电子、电气设备系统微电子化，使电子系统对电磁脉冲的敏感性和易损性日趋严重，尤其是随着高功率微波武器以及电磁脉冲弹等新概念电子战武器的出现，对电子系统抗电磁打击的要求提上日程。
