摘要

色散媒质中瞬变电磁波的传播与散射等问题的计算分析是比较困难的，特别是在时域直接分析更加困难，本文采用时域的有限差分法（ＦＤ－ＴＤ）来分析色散媒质中的瞬变场能直观可靠地反映其特性，为色散媒质中瞬变场的分析与研究和对目标识别、电磁兼容和隐形技术等领域的理论及应用研究提供了一种简便有效的数值计算方法．

Abstract

Study and computation of transient electromagnetic propagation and scattering in dispersive media are difficult

especially

the direct analysis in time-domain.A modified finite-difference in time domain（FD-TD） method for computation of transient propagation and scattering fields is presented in this paper.The results obtained from this way are visualable and faithful

and an efficient direct way of numencal modelling to study the characteristic of transient fields in dispersive media and the wideband problems in research fields of target detection

eletromagnetic compatibility and stealth technology is provided as well.
