Aspects of light propagation in anisotropic dielectric media

Some aspects of light propagation in local anisotropic nonlinear dielectric media at rest in the limit of geometrical optics are investigated. Natural and artificially induced anisotropies in dielectric materials are discussed. Analogies are proposed in such way that, as far as light is considered, kinematic aspects of some cosmological models are recovered. Particularly, analogue models for isotropic and anisotropic cosmologies are presented.
