Non-reflecting dispersive media

Hellberg, Rasmus; Karlsson, Anders LU and Thärning, Peter (1992) In Smart Materials and Structures 1(4). p.46-341
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. A time-domain Green functions technique is used to solve the inverse problem.
