The propagation characteristics of ridged circular waveguides are analyzed by using 2D finite-difference frequency-domain (2D FDFD). Based on the 2D FDFD method in a cylindrical coordinate system, general difference formulas for the ridged circular waveguide are deduced, and modified difference form

Abstract
The 2D finite‐difference frequency‐domain method combined with the surface‐impedance boundary condition is applied for the analysis of dispersion characteristics of lossy metal waveguides. Six electromagnetic field components are involved in the final eigen equation. By solving the eigen equation, the method finds the propagation constants for a given frequency. © 2004 Wiley Periodicals, Inc.

In this article, a general full-wave two dimensional finite difference frequency domain (2D-FDFD) method is presented that could be used to analyze general circular multi-layered multi-conductor guiding structures. The FDFD method is mainly used to get the dispersion curves for these structures. The
A conformal first-order or Leontovic surface-impedance boundary condition (SIBC) for the modelling of fully three-dimensional (3-D) lossy curved surfaces in a Cartesian grid is presented for the frequencydomain finite-difference (FD) methods. The impedance boundary condition is applied to auxiliary
Full-wave analysis of circular guiding structures completely filled with ferrite by using the finite difference frequency domain method is presented. The ferrite is assumed to be azimuthally magnetized to remanence. Emphasis is placed on the TE 0m modes that are rotationally symmetric. These modes e
