An approach based on the finite element method (FEM) with the rectangular-parallelepipd edge element is proposed for the analysis of electromagnetic waveguide bends. Here, to be permissible for analysis of various electromagnetic waveguides, the analytical relations in the uniform waveguide are cons

Abstract
The finite element method is formulated in such a way that the electromagnetic solution of an excited cavity formed from an N‐port waveguides junction leads directly and naturally to circuit characteristics of this junction. The use of edge‐elements eliminates nonphysical solutions. The reliability of the method is assured compared to a penalty method. Accuracy of the method is demonstrated through the presentation of results for a waveguide T‐junction, while its efficiency is proven through the presentation of results for two case studies of a finite step discontinuity and a finline T‐junction. © 1993 John Wiley & Sons, Inc.
