Abstract

A method for the time‐domain simulation of electromagnetic wave propagation in ferromagnetic materials displaying frequency‐dependence and saturation is developed. The technique is based on incorporating into transmission‐line modelling (TLM) a non‐linear system to describe the frequency‐dependent permeability and saturation properties of a ferromagnetic material. The approach is validated for the linear (small‐signal) case by the calculation of the normal incidence reflection coefficient of a metal backed ferrite tile. Results are also shown for the non‐linear (large‐signal) case where the material is driven into saturation. Copyright © 2004 John Wiley & Sons, Ltd.

A transmission line matrix (TLM) model suitable to simulate the propagation of waves in moving anisotropic continuous media is presented. As is well known, an electromagnetic wave propagating in a general medium, moving with respect to its source, experiences a drag by the own medium, which involves
