Abstract:

The correct formulation for scattering from objects near an interface is described. The method used to couple the related scattered solution to a range-dependent waveguide is then shown. Calculations for elongated elastic objects such as elastic spheroidal solids and shells are then incorporated into the formulation, and the effect of the imbedding of objects in the waveguide are illustrated, particularly in the vicinity of an ocean surface.
