证明和讨论了有关活性介质或超材料的一些结果。特别是，我们考虑介电常数、磁导率、波矢量和折射率，并讨论稳定性、折射、增益和因果关系产生的基本限制。
Several results concerning active media or metamaterials are proved and discussed. In particular, we consider the permittivity, permeability, wave vector, and refractive index, and discuss stability, refraction, gain, and fundamental limitations resulting from causality.
