Non-reflecting dispersive media
(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.
