Comments on the Use of EM Solvers for Waveguide Feed Analysis

In this case, the authors of the article were generous enough to allow CST engineers to examine the septum model and utilize all three of Microwave Studio’s general purpose high frequency solvers (transient domain, frequency domain and integral equation) on it. A refined mesh is always necessary to obtain accurate results in all 3D ectromagnetic solvers. In Figures 1 and 2, the mutual coupling and return loss are shown respectively after mesh convergence was obtained in each case. A high degree of agreement between the different solvers is apparent, particularly on the mutual coupling which is at a more appreciable level.
