Paper Abstract

The scattering of acoustic waves from three dimensional compressible scatterers is considered. Particular attention is paid to cases where the scatterers have moderate magnitude in compressibility contrast and nondimensional wavenumber. A perturbation method based on Pade approximants is developed. It is shown that the Pade approximant model allows one to represent and evaluate the characteristic features such as internal resonances and mode shapes of the scattered pressure field. These modes are a function of the compressibility contrast and the frequency of the incident pressure wave. Numerical results are in agreement with the analytical solutions for scattering from a sphere.
