Elastic Scattering from a Spherical Body Eccentrically Located within a Sphere:Theoretical Derivation

摘要

The scattered fields from a spherical body eccentrically located within a hostsphere are found by a derivation that satisfies the boundary conditions at both interfaces. The source, which may be composed of any linear combination of S and P waves, is also arbitrarily located within the host sphere. The scattering system has applications in seismic scattering, since the scattering interaction between a scatterer and the Earth's surface is significant when the scatterer is located near the surface. This interaction can affect subsequent seismograms.
