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.
