Abstract
In this paper a coupled-mode method for computing the wave field scatt ered by three-dimensional, axisymmetric fluid objects is presented. Th e method provides a unified approach to solving three-dimensional scat tering problems for axisymmetric objects in free space, in a waveguide , or partially or fully buried in a basement. Numerical computations o f 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 resu lts are available. [S0001-4966(97)03412-7].
