Abstract

A novel analysis technique based on the method-of-lines and mode-matching is used for investigating the distribution and amplitudes of higher-order modes at any plane inside microstrip structures. The fundamentally ill-conditioned problem of transforming high order mode amplitudes across two-port networks is eliminated by following an approach similar to circuit based nodal analysis. An interdigital filter is presented as a case study
