In this paper, a two dimensional (2D) finite‐difference frequency‐domain (FDFD) method is applied to analyze the dispersion characteristics of ferrite devices. The FDFD formulation for ferrite devices is built from the integral form of Maxwell's equations. After implementing all the boundary conditions, the finite‐difference formulation is concluded as an eigen equation and then constructed by a highly sparse matrix. By solving the matrix‐eigen equation, the dispersion characteristics of ferrite devices for a given frequency can be obtained. In order to verify the validity of the proposed method, an infinite ferrite‐filled waveguide is examined and the numerical results are compared to both the theoretical result and the 3D finite‐difference time‐domain (FDTD) numerical result. © 2004 Wiley Periodicals, Inc.
