✦ Synopsis

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 a wave velocity dependent on the direction of propagation. In this work, we present a first approach for the case of uniform movement of an anisotropic dielectric medium with respect to an electromagnetic source. Although the technique allows for quantitative results, special attention is devoted to the simulation of wave fronts, distorted elliptical fronts, because a particular kind of 'anisotropy' appears, even in an isotropic medium.

In this paper, a novel TLM algorithm for electromagnetic wave propagation in chiral media is presented. One of the main characteristics of the electromagnetic response of such media is the rotation of the polarization plane. The obtained TLM results for a monochromatic source are compared with the t

## Abstract Cabeceira et al. recently presented a time‐domain analysis of wave propagation in a Tellegen medium [1]. Their analysis is ill‐founded because (i) the existence of any Tellegen medium is not tenable within modern electromagnetic theory; and (ii) the constitutive relations employed are n
