Abstract :
The finite element method is formulated in such a way that the electromagnetic solution of an excited cavity formed from an N-port waveguide junction leads directly and naturally to circuit characteristics of this junction. The use of edge elements eliminates nonphysical solutions. The reliability of the solution 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 a case study of a finline step discontinuity.<>
