Dispersive effective material parameters for Maxwell's equations

In English

Författare

Summary, in English

We study 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. We essentially

require that the effective material parameters should produce the

same dispersion relations as the heterogeneous problem, which

implies the effective material is primarily connected to the phase

velocity of the waves. Material parameters which exhibit temporal

dispersion only, can be defined if the propagation direction is

fixed.
