Non-reflecting dispersive media

Hellberg, Rasmus ; Karlsson, Anders LU and Thärning, Peter (1992) In Technical Report LUTEDX/(TEAT-7020)/1-12/(1992)
Abstract
The modeling of non-reflecting one-dimensional dispersive media is discussed.

The media are temporal 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 so that the media do 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. Atime domain Green functions technique is used to solve the

inverse problem.
