Paper Abstract

A method for modeling reflectionless conductive dispersive media is presented. The media are either half-spaces or finite dispersive slabs with a spatially varying impedance. The problem of finding reflectionless media for plane waves at normal incidence 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. The inverse problem is solved by a time domain Green functions technique. It is seen that non-reflecting half-spaces can be constructed in a number of different ways, whereas non-reflecting slabs only can be found if the backwall is non- conducting.
