Causality and electromagnetic properties of active media.

Bertil Nistad1, Johannes Skaar.   

Abstract

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.
