我们研究的行为，在材料中的磁导率和介电常数张量的主要元素并不具有相同的符号波的传播。我们发现，各种各样的效果可以实现在这样的媒体，包括负折射，近场聚焦，和高阻抗表面反射。特别是，这些材料的双层可以将场分布从一侧转移到另一侧，包括近场，而不需要内部指数增长波。
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.
