Analysis of 3D ferrite‐loaded waveguide discontinuity problems

In this article, an approach is presented to compute the scattering parameters of the ferrite-loaded waveguide discontinuity using the finite-element method (FEM) and perfectly matched layers (PMLs). The propagation constants of a uniform ferrite-loaded waveguide are first calculated to validate the proposed approach. Then a 2D ferrite-loaded discontinuity problem is computed to further confirm the accuracy of the approach. Finally, several 3D discontinuity results are given to show the efficiency and generality of the approach. © 2003 Wiley Periodicals, Inc. Int J RF and Microwave CAE 13, 341–347, 2003.
