Calculation and Optimization of 3D Waveguiding System with Help of Integral Equation Method

Abstract

For 3d waveguiding system calculations we used the Electric Field Integral Equation (EFIE) model, applied to infinitely thin, perfectly conducting waveguide surfaces. The solution represents induced current, from which the field in the device is obtained. With the help of this method an asymmetric mode converter TE01-TE11 was simulated and optimized for maximum efficiency. We have also studied a helically corrugated structure, which is used in pulse compressors, and analyzed the structures dispersion curves and compared it with measurement results.

Synthesis of multimode waveguide converters using full-wave EFIE field analysis method

“…In this paper we propose using EFIE (Electric Field Integral Equation) solver [4,5]. The synthesis use the fields on the waveguide wall which are simply rewritten in terms of surface current directly calculated with EFIE approach:…”
