Scattering of a pulsed Rayleigh wave by a spherical cavity in an elastic half space

Artikel i vetenskaplig tidskrift, 1983

The time-dependant scattering by a spherical cavity in an elastic half space is considered. The incoming wave is a pulsed Rayleigh wave. The stationary part of the problem is solved by the T-matrix method, and an integration in frequency is perforemd with a modified gaussian weight function. The displcsement components at some points on the surface of the half space are computed and shown in a number of plots.
