Abstract

Abstract

A new method, termed netwok model decomposition method, is presented for the evaluation of cut-off frequencies of an arbitrary shaped waveguide with arbitrary filling. Through discreting the region studied, a topological model and the corresponding network model are established based on the differential orms in electromagnetic field theory. A general algorithm for evaluating the cut-off frequenciess of an arbitrary shaped waveguide with arbitrary filling is constructed by using the diakopti node analysis in electrical network theory. The algorithm is applied to several typical waveguides with the validity and effectiveness of the method demonstrated.
