Research Progress of Materials Shielding Effectiveness on Electromagnetic Pulse

首先总结了国外电磁脉冲的研究现状及屏蔽效能的测试方法,并分析了国内电磁脉冲屏蔽效能的测试方法及根据频域测量结果估计时域响应研究进展,然后介绍了屏蔽效能频域和时域表征方法,特别是近几年来电磁脉冲屏蔽效能的表征方法,最后指出了当前电磁脉冲屏蔽效能研究中需解决的问题及今后研究方向,对电磁脉冲作用下材料屏蔽效能的研究具有指导意义。

First, the recent advances of electromagnetic pulse（EMP） and the measurement methods of shielding effectiveness（SE） abroad are summarized, and the domestic measurement methods and the research on evaluating the time domain response according to the frequency domain result are analysed. Then, the expression methods of SE in frequency domain and time domain are described with emphasis on the recent methods of SE on EMP. Finally, some questions to be solved and the research direction in future are pointed out, which is instructive for the research on SE.
