Design of reflextionless slabs for transient electromagnetic waves
(1994) In Technical Report LUTEDX/(TEAT-7032)/1-21/(1994)- 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) - A method for modeling reflectionless conductive dispersive slabs is presented.
