title: Electromagnetic wave propagation in media with indefinite permittivity and permeability tensors.
abstract: We study the behavior of wave propagation in materials for which not all of the principal elements of the permeability and permittivity tensors have the same sign. We find that a wide variety of effects can be realized in such media, including negative refraction, near-field focusing, and high impedance surface reflection. In particular, a bilayer of these materials can transfer a field distribution from one side to the other, including near fields, without requiring internal exponentially growing waves.
