The author studied how effective material parameters can be defined for Maxwell's equations when taking dispersion into account. The reasoning is based on 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 can be defined if the propagation direction is fixed. © 2006 Wiley Periodicals, Inc.
