Özet
An inclusive method is introduced for the analysis of different types of inductively loaded rectangular waveguides with dielectric and/or metallic obstacles. The proposed method utilizes the efficiency of the generalized scattering matrix (GSM) method on scattering analysis and the flexibility of the method of moments on problem configuration. The inductive metallic discontinuities are treated as a dielectric medium with high conductivity and the scattering analysis is accelerated by several cost reduction attempts in conjunction with GSM method and procedure of method of moments. The examined approach is tested against several structures including a metal insert filter, anH-planefilter, and a dielectric-metal obstacle-loaded waveguide both for the dominant mode region and the double-mode region. The convergence analyses on the number of calculated modes and the size of the discretized cells in the computational procedure are carried out for a comprehensive explanation of the numerical analysis. The accuracy of the method is compared to commercial software based on the finite element method. The proposed method is particularly competent for the frequency analysis of metallic and inhomogeneous dielectric discontinuities horizontally aligned in cuboid shapes.
