The direct and inverse problem for obliquely incident transient elastodynamic waves

Hellberg, Rasmus and Karlsson, Anders LU (1997) In Technical Report LUTEDX/(TEAT-7057)/1-27/(1997)
Abstract
The direct and inverse scattering problems for a plane-stratified viscoelastic

medium excited by a transient plane wave of SH or P-SV type are treated.

The viscoelastic medium is characterized by two time and space dependent

memory functions and a spatially dependent density. The direct and inverse

problems are solved by a time-domain wave propagator method that is related

to the Green functions technique and the imbedding method. The definition of

the wave-propagators is based upon a wave-splitting technique where the total

wave is split into generalized left and right going components. A numerical

algorithm for the inverse problem is presented for the P-SV case.
