TLM simulation of electromagnetic wave propagation in anisotropic moving media

A TLM (Transmission Line Matrix) model suitable to simulate the propagation of waves in moving anisotropic continuous media is presented. As it 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, a 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.
