Research progress of materials shielding effectiveness on electromagnetic pulse

First,the recent advances of electromagnetic pulse(EMP) and the measu rement methods of shielding effectiveness(SE) abroad are summarized, and the do mes tic measurement methods and the research on evaluating the time domain response ac cording to the frequency domain result are analysed. Then, the expression method s o f SE in frequency domain and time domain are described with emphasis on the rece n t 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.
