On the multiple scattering of waves from obstacles with solid-fluid interfaces
Abstract
A T-matrix formalism is developed for elastic wave scattering by multilayered regions with solid-fluid interfaces. The approach is based on the use of Green's dyadic in an integral representation. Numerical results are presented for rotationally symmetric bodies in a fluid; the wavelengths considered are in the longwave and resonance regions. Consideration is also given to complex wave numbers, the moduli of which are less than the inverse power of some characteristic body dimension.
