Abstract
An efficient hybrid method is proposed for analysing discontinuities in a rectangular waveguide. With only a small number of meshes around discontinuities, the typical finite element method is shown to give an exact solution through several iterative updates of the boundary conditions. To demonstrate the validity of the proposed method, a simple circular aperture in a rectangular waveguide is analysed and results compared with those of another method
