快上升前沿电磁脉冲与目标腔体的孔腔共振效应研究
-
摘要: 利用时域有限差分方法(FD-TD Method)研究了快上升前沿电磁脉冲(FREMP)对目标腔体的孔腔共振效应。研究表明:由于FREMP的高频分量丰富,使得FREMP更容易通过目标腔体上的孔缝,与目标腔体发生孔腔共振。由于孔缝的对外辐射,振荡幅度将逐渐减弱。Abstract: The purpose of this paper is to use the FiniteDifference TimeDomain (FDTD) method to study numerically t he resonant effects of FREMP into a cavity through a slot. Computational data i ndicate that FREMP is easier to resonate with a cavity through a slot for the plentiful high frequencies of FREMP. Because of the radiation outward, the a mplitudes of resonant signals attenuate slowly.
