A full-wave analysis of a coaxial waveguide slot bridge using the Fourier transform technique

Abstract

Electromagnetic wave scattering from a coaxial waveguide slot bridge is theoretically investigated. The Fourier transform/series technique is utilized to constitute a set of simultaneous equations for the discrete modal coefficients. The residue calculus is applied to transform the scattered-field integral representations into fast-converging series forms. Numerical computations illustrate the behavior of scattering in terms of the slot geometry, the incident mode, and the operating frequency.
