摘要：

根据理想脉冲电磁场穿透良导体屏蔽壳层的能力，给出了理想脉冲电磁场在良导体中传播的波动方程。计算了理想脉冲平面电磁波的穿透幅度衰减因子，并分析了理想脉冲电磁波和简谐电磁波的幅度衰减因子，根据幅度衰减因子相同的原则，给出了理想脉冲电磁波的简谐电磁波等效频率，为电磁屏蔽防护技术提供设计理论参考。

Abstract:

The capacity of the ideal strong electromagnetic pulse to penetrate through the goodconductor enclosure is discussed, and the wave equation of the ideal pulse electromagnetic transmitted in the good conductor is presented. The penetrating amplitude attenuation of the ideal pulse electromagnetic wave is calculated, which is compared with harmonic electromagnetic wave. Based on the principal of the equal amplitude attenuation factor, the equivalent harmonic frequency of the ideal pulse electromagnetic is presented, which provides a theory for the design of the electromagnetic shielding and defending technology.

Key words: pulse electromagnetic, wave equation, reduction factor
