摘要
在时域有限差分方法中,吸收边界条件的吸收特性直接影响到时域有限差分的结果,本文提出了两种改善透射边界条件的方法:多层反射损耗方法和超吸收方法。
The time domain finite-difference(FDTO)method has already been applied to many areas of electromagnetic scattering, radiating and inverse scattering.Absorbing boundary condition plays a critial role in FDTD.In the paper, authors apply an effectlve transmitting boundary condition to improve the results of FDTD,and present two new methods,losa layers method and superabsorption method,to improve the transmitting boundary Condition.[
