The direct and inverse problem for obliquely incident transient elastodynamic waves
Author
Summary, in English
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.
