Network modelling of interacting capacitive irises and steps in waveguide
Abstract
Consideration of the problem of the TM(LSE) excitation of aperture-type discontinuities or TE(LSM) excitation of obstacle-type discontinuities in a multimode situation. The problem reduces to that of analyzing a cascade of lumped multiports connected by a finite and usually small number of transmission lines. The multiports are described by means of their canonical Foster form. The problem then consists in extracting poles and residues directly from a Rayleigh-Ritz variational solution of the field problem. This solution yields an accurate wideband equivalent network with explicit, geometry-dependent element values.
