摘要
利用时域有限差分方法( F D T D M ethod)研究了快上升前沿电磁脉冲( F R E M P)对目标腔体的孔腔共振效应。研究表明:由于 F R E M P 的高频分量丰富,使得 F R E M P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。
The purpose of this paper is to use the Finite Difference Time Domain (FD TD) method to study numerically the resonant effects of FREMP into a cavity through a slot. Computational data indicate 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 amplitudes of resonant signals attenuate slowly.
