| Abstract: |
| 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. |
