| Abstract: | 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. |
