A Finite-Element Model for Ocean Acoustic Propagation and Scattering

Abstract

The finite-element technique has the potential to provide a very accurate treatment of the physics of acoustic-wave propagation in inhomogeneous media. This article describes the development of a finite-element model for acoustic propagation in complex ocean environments and its validation. The computational model can handle range and depth dependence in both sound speed and density, as well as rapid variations in bottom topography. Keywords: Reprints; Acoustic waves; Elastic waves; Seismic waves.
