On the Non-Dispersiveness of a Composite of Non-Layered Dispersive Media

Abstract

We studied the question whether a composite of non-layered dispersive media be effectively non-dispersive using a line source. Since the recovery of the reflection coefficient of a medium (half space) from observed reflected waves in the line source case is not as direct as in the plane wave case, an alternate approach is suggested to help decide if a given medium is non-dispersive. This approach which is based on a simple measure is used in several problems, both theoretical and FDTD simulations.
