Time domain inversion techniques for electromagnetic scattering problems

Kristensson, Gerhard LU and Krueger, Rober J. (1992) In Invariant imbedding and inverse problems p.1-29
Abstract
This paper presents a review of and a comparison between two different methods

to solve an inverse scattering problem in the time domain. The problem

is that of propagation of transient electromagnetic waves in spatially inhomogeneous

slabs of finite length. The permittivity and conductivity profiles

are assumed to vary only with depth and the scattering problem is thus onedimensional.

Several algorithms to solve the direct and inverse scattering

problems for continuous and discontinuous permittivity profiles are suggested.

Some of these algorithms have not been published before. The aim of this paper

is to compare and review these methods. More specifically, the... (More)
This paper presents a review of and a comparison between two different methods

Several algorithms to solve the direct and inverse scattering

Some of these algorithms have not been published before. The aim of this paper

is to compare and review these methods. More specifically, the numerical

performance of the invariant imbedding approach (layer-stripping)and the

Green functions formulation (downward continuation)is compared. Some

new results based upon time reversal techniques for a lossless slab are presented

in an appendix. (Less)
