A Mode-Matching Solution for the Study of Cylindrical Waveguide Bifurcation via Closed-Form Coupling Integrals

摘要： In this paper, we present a mode-matching technique formulation for the rigorous electromagnetic analysis of a circular waveguide bifurcated into circular and coaxial domains. A generalized scattering matrix is obtained for relating the modal field amplitudes in each of the waveguides, and we were able to obtain closed-form solutions for all the associated coupling integrals. We present a series of validation results showing that the technique introduced in this work can model accurately and efficiently a class of cylindrical waveguide devices.
