摘要

本文发现将一阶Mur吸收边界条件分别应用到x－t，y-t，z－t平面上两相邻对角节点时，电磁波的反射误差可以互相抵消，从而提出了二重一阶Mur吸收边界条件（TwofoldMur＇sfirst－orderABC，简称TMFABC）．TMFABC可以很方便地应用到多层结构上去，吸收效率比一阶Mur吸收边界条件及其超吸收算法明显提高，尤其在低频端的效果更好，而且TMFABC对衰减波的吸收也很有效我们将TMFABC移植到一个时域有限差分（FDTD）程序中，用来提取多导体传输线的电路模型参数，取得了良好的效果

Abstract

It is found that the reflection error of Mur’s first-order absorbing boundary condition can be cancelled effectively by applying the ABC twice to an electromagnetic field on two diagonally neighboring nodes on the x-t

y-t and z-t planes

according to which a twofold Mur’s first-order ABC（TMFABC） is developed. It is very convenient to apply TMFABC to multilayer structures. The absorption efficiency of TMFABC is obviously better than that of Mur’s first-order ABC and its super algorithm

especially at lower frequencies. A FDTD software using TMFABC has been written to extract the circuit model parameters of transmission lines in high-speed integrated circuits.
