Abstract

Recently the application of the equivalence principle to the analysis of dielectric- loaded cavities was suggested. In comparison to other methods this method transforms the problem of .solving a three-dimensional discontinuity into a two-dimensional problem over the surface of the inserted body, which drastically reduces the size of the involved characteristic matrix. Now this method has been extended to the analysis of dielectric-loaded cavities which are coupled to waveguides. In particular, if the cavity is a waveguide section which is coupled at both sides to similiar waveguides, the method can then describe scattering inside infinitely long waveguides.
