静电场边值问题的矩量法解

本文采用修正格林函数积分方程的矩量法数值解技术求解静电场边值问题。这种方法具有较边界积分法积分域小的特点,不仅有高的计算效率和精度,尤其适用于有无限延伸导体边界的边值问题。本文着重讨论与传输线问题等效的边值问题,这是典型的二维静电场问题,对高频和微波技术有重要的实用价值。本文方法也适用于三维静电场问题和交变电磁场问题。

MOMENT-METHOD SOLUTION OF STATIC-ELECTRIC BOUNDARY-VALUE PROBLEMS

A new approach to numerical solution of the boundary-value problems of static-electric fields, the Modified Green Function kernel integral equation and its moment-method solution, is presented. Due to the significient compression of integration region of the integral equations, the present approach is numerically effective and is especially suitable to the problems with infinite conductor boundary. The emphasize is paied on the analysis of transmission lines, which are the typical boundary-value problems of two-dimension and are very useful to the high-frequency and microwave techniques as well.The analysis method to the 3-dimensional counterparts of the problems is similar, and.the extended applications to the problems of variable electromagnetic fields are proved successful.
