RECONSTRUCTION OF BI-ISOTROPIC MATERIAL PARAMETERS USING TRANSIENT ELECTROMAGNETIC-FIELDS

A non-iterative time-domain method far solving the inverse scattering problem for the temporally dispersive, linear, homogeneous, and bi-iso tropic slab at normal incidence is presented. The inverse scattering p roblem is to determine (finite time traces of) the susceptibility kern els of the medium given (finite time traces of) the reflection and tra nsmission kernels, which are obtained by deconvolution of the scattere d fields. Two numerical examples illustrate the method for this kind o f noisy data. A series representation of the solution of the direct pr oblem is obtained as well. (C) 1998 Elsevier Science B.V.
