Acoustic field induced in spheres with inhomogeneous density by external sources
GC Kokkorakis, JG Fikioris - The Journal of the Acoustical Society of …, 2004 - pubs.aip.org
Acoustic or electromagnetic fields induced in the interior of inhomogeneous penetrable
bodies by external sources can be evaluated via well-known volume integral equations. For
bodies of arbitrary shape and/or composition, for which separation of variables fails, a direct
attack for the solution of these integral equations is the only available approach. In a
previous paper by the same authors the scalar (acoustic) field in inhomogeneous spheres of
arbitrary compressibility, but with constant density, was considered. In the present one the …
