A boundary integral equation method for acoustic scattering in a waveguide with nonplanar surfaces

A boundary integral equation method (BIEM) is formulated to compute the scattering of underwater sound from compact deformations of an oceanic waveguide’s surfaces. The method involves only integrations over the finite area of the waveguide surface deformations. Numerical computations are given for...

Zusammenfassung:A boundary integral equation method (BIEM) is formulated to compute the scattering of underwater sound from compact deformations of an oceanic waveguide’s surfaces. The method involves only integrations over the finite area of the waveguide surface deformations. Numerical computations are given for specific deformations of the ocean floor.
