Up to this point, we have concentrated our attention on issues conserning the fields and waves in simple media, i.e., linear, nondispersive, and isotropic media, For a simple medium, the constitutional parameters are assumed to be constant scalars and frequency independent. In fact, no medium can always be a simple medium except vacuum. Most media can only be approximated as simple media under certain conditions.
