Verified simulation of waveguide inhomogeneities in Keysight EMPro 2017 software

Abstract

In this paper numerical simulation of inhomogeneities in rectangular and circular waveguides at microwave, using the finite element method in Keysight EMPro 2017 CAD, with experimental data verification are considered. A sphere is used as a typical heterogeneity. Four samples of materials are considered: copper, paraffin, acrylic resin and texolite. A description is given for the modeling the electrophysical parameters of these materials in a computer-aided design system. A comparison of numerical and experimental data for a rectangular waveguide is made. The selected materials are of primary concern for the study and demonstrate various electrophysical parameters.
