Dispersive effective material parameters

Research output: Contribution to journalArticlepeer-review

Abstract

The author studied how effective material parameters call be defined for Maxwell's equations when taking dispersion into account. The reasoning is based oil the concept of dispersion relations, and is consequently primarily concerned with lossless media. The author essentially required that the effective material parameters should produce the same dispersion relations as the heterogeneous problem, which implies that the effective material is primarily connected to the phase velocity of the waves. Material parameters that exhibit only temporal dispersion call be defined if the propagation direction is fixed. (c) 2006 Wiley Periodicals, Inc.
