摘要
该文详细地阐述了广义完全匹配层理论（Ｇｅｎｅｒａｌｉｚｅｄ Ｔｈｅｏｒｙ ｏｆ Ｐｅｒｆｅｃｔｌｙ Ｍａｔｃｈｅｄ Ｌａｙｅｒｓ，简称广义 ＰＭＬ），并应用广义ＰＭＬ作为时域有限差分法（Ｆｉｎｉｔｅ－Ｄｉｆｆｅｒｅｎｃｅ Ｔｉｍｅ－Ｄｏｍａｉｎ Ｍｅｔｈｏｄ，简称 ＦＤＴＤ）网格空间的吸收边界仿真计算了天线的近场。所得结果与解析方法（口径积分法ＡＩ，平面波谱法ＰＷＳ）完全一致，从而证明了该方法能应用于三维天线与天线罩的分析计算。
This paper discusses Generalized Theory of Perfectly Matched Layers, then applies it to the simulation of antenna near-- field with Finite -- Difference Time -- Domain Method, with the result which agrees very well with established theoretic methods. This method can simulate actual electromagnetic field in space and provide a new method for the design of antenna and radome combination with accessories.
