Modeling three-dimensional propagation in an oceanic wedge using parabolic equation methods

Abstract

In this paper the predictions of azimuthally uncoupled and azimuthally coupled parabolic equation (PE) methods for three-dimensional acoustic propagation in a penetrable oceanic wedge are compared. The individual modes of the waveguide at the source position are used as the initial field for the PE methods and the resulting PE fields are compared to the ray diagrams of three-dimensional adiabatic mode theory.
