| 摘 要： | 将Ａ．Ｐ．Ｚｈａｏ提出的与媒质无关的完全匹配层吸收边界推广到色散媒质中，推导出了用于色散媒质的无反射完全匹配条件。并对导电媒质进行了数值实验，结果十分理想。与Ｑ．Ｈ．Ｌｉｕ的方法相比，该方法可以应用到更复杂的媒质中。而与Ｓ．Ｄ．Ｇｅｄｎｅｙ的各向异性媒质吸收层相比，在角区的处理要简单得多，更适合于时域有限差分法，对于三维问题更是如此。

| Abstract: | Extension of material independent Perfectly Matched layer to dispersive media is made in this paper and perfectly matched condition for dispersive media is derived. Numerical experiment is done in lossy media and good result is achieved. Comparing with Q.H.Liu's method, the method can be used to more complicate material and comparing with S.D.Gedney's anisotropic material absorber, calculation in the corner region is more simple therefore, it is more suitable for FDTD, especially in three dimension case. |
