Description

Interaction of sound waves with rough surfaces has attracted attention owing to its significance in several fields. Scattering from wavy surfaces, seabeds, and ice in ocean acoustics has been extensively studied, as has scattering in rough dielectric waveguides, such as optical fibers. In either of these problems the fields can be assumed to be represented by a single scalar potential. The problem we consider here concerns the propagation of guided elastic waves in a planar waveguide having rough surfaces, with compressional and shear potentials that are coupled at each interface.
