摘要

本文用ＦＤＴＤ法处理复合型导体结构中电磁场的耦合和传输时，用一种子域连接法建立数学模型．以分析波导元件散射特性和波导口径面天线的辐射特性为例来说明这种方法的具体运用．这种方法具有节省计算空间和计算时间、建模灵活多样等优点．

Abstract

A sub region connection method is developed when we use the FDTD method in analyzing compound conducting structures.The transmission and reflection characteristics of waveguide elements and the radiation of waveguide aperture antenna are taken as numerical examples.This method has the advantages of saving computational space

reducing running time

and being flexible in setting up FDTD grid.
