Scattering of a Transient Plane Compression Wave by a Spherical Inclusion in a Biot Medium.

Abstract

The scattering of an arbitrary transient plane wave by a spherical inclusion in a Biot medium is modeled, by applying the single frequency steady state solution of Zimmerman and Stern to the discrete Fourier components of the transient signal, and assuming linear superposition. The solution of Zimmerman and Stem is an analytical series solution. Its accuracy is mainly determined by computation errors and the convergence of the series. The incident pulse can be any combination of Biot fast and slow waves. The theoretical results for certain cases are shown. They are also compared to experimental measurements. This work is an integral part of an effort to model the acoustic response of buried objects in the ocean sediment.
