Transient direct and inverse scattering for inhomogeneous viscoelastic media:Obliquely incident SH mode

Karlsson, Anders LU and Corones, James (1988) In Inverse Problems 4(3). p.643-660
Abstract
A stratified viscoelastic medium in the time domain is characterised by two creep compliances that are functions of time and depth, and a density that is a function of depth. In this paper the direct scattering problem of a plane horizontal shear wave obliquely incident on a stratified viscoelastic medium is treated in detail. A general discussion of the corresponding inverse problem is given. A specific algorithm is given for the inverse problem for a viscoelastic halfspace with a depth-dependent density and a time-dependent creep compliance. The input to the algorithm are reflection data from two angles of incidence and the result is the density profile and the creep compliance.
