摘　　要：本文介绍一种分析波导不连续性的数值计算方法 ,采用有限差分法和共轭梯度法对根据矢量偏微分算子理论得出的电磁波基本方程进行求解 ,由此计算出反射系数和传输系数 。This paper presents a numerical method for the analysis of waveguide discontinuities. The basic equations of electromagnetic field derived from vector partial differential operator theory are solved by using finite difference method and conjugate gradient method, and the reflection coefficient and transmission coefficient are obtained. The method is demonstrated by an example of a rectangular waveguide with an inductive diaphragm.
