Simple, efficient, and accurate analysis of the flanged parallel-plate waveguide

The flanged parallel-plate waveguide is analysed based on the method of Kobayashi potential (KP) using Fourier function space. presentation free from intricate mathematics. Standard integral identities are used for problem formulation, without direct use Weber-Schafheitlin (WS) integrals. space exploited construction governing linear equations instead Jacobi polynomials. A simple strategy suggested evaluation required improper Near-field results validated through convergence analysis. Far-field patterns compared with predictions surface equivalence theorem (SET).
