Design of reflextionless slabs for transient electromagnetic waves

Abstract
A method for modeling reflectionless conductive dispersive slabs is presented.

The slabs are impedance matched to the surrounding half-spaces and are

temporally dispersive with a spatially varying impedance. It is shown that the

effects from the variation of the impedance can be matched by the temporal

dispersive effects and the conductivity so that for a normally incident plane

wave the slab does not reflect any field regardless of the shape of the incident

transient field. The problem of finding reflectionless media is formulated as

an inverse problem where the constitutive relation is to be determined as a

function of depth given a reflection kernel which is zero.... (More)
