Coupled-mode modelling of acoustic scattering from three-dimensional, axisymmetric objects

Thumbnail
Abstract
In this memorandum a coupled-mode method for computing the wavefield scattered by three-dimensional, axisymmetric objects is presented. The method provides a unified approach to solving three-dimensional scattering problems for axisymmetric objects in free-space, in a waveguide, or partially or fully buried in a basement. Numerical computations of scattering from finite cylinders in free space and embedded between two half-spaces are presented. Also, the method is used to compute the scattering from an infinitely long cylinder for which analytical results are available. The fluid approximation is used for both the object and the surrounding medium.
