Abstract

Summary form only given. The concept of group velocity is critical when applied to an absorbing (or gain), homogeneous dielectric material because V/sub g/ may be greater than c, and it can even be negative in some circumstances. We discuss the case in which a 1-D PBG structure displays anomalous effective index behavior, not as a result of gain or absorption, but as a result of scattering.
