Intensity Vectors of Sound Scattering by a Spherical Shell.
Abstract
Acoustic intensity vector plots can illustrate vividly the power flow in an acoustic fluid. It is the main purpose of this memorandum to examine, by means of acoustic intensity vector plots, the distortion of the incident sound field due to the presence of a spherical shell whose target strength spectrum contains well-defined resonant peaks. Mathematical formulae are given from which target strength spectra and acoustic intensity vectors are calculated. The excitation is a time-harmonic plane wave. Intensity vector plots show the considerable distortion of the incident sound field that may be present when an elastic scatterer is excited at a resonant frequency.
