Rigorous field theory analysis of quasiplanar waveguides
Abstract
An accurate field theory solution for calculating the hybrid eigenmodes of quasiplanar structures is introduced which includes the influence of the finite strip thickness and the waveguide housing grooves. Using the transverse-resonance method, the size of the characteristic matrix equation is kept constant even for an increasing number of dicontinuities. Dispersion characteristics of various structure consisting of at least one isolated strip are presented. The fundamental EH modes mainly depend on the finite strip thickness, while increasing waveguide grooves lead to a significant reduction of higher-order-mode cutoff frequencies.
