The physics of sound propagation in the ocean is briefly reviewed. The mathematical
foundation of the most widely used acoustic models (ray, mode, fast field, parabolic …

Many methods exist for determining the solution of linear ocean acoustic wave propagation
problems. A number of solutions have been found by conventional analytic methods. These …

In this study a model predicting the electromagnetic wave propagation has been developed.
The model is initialized with a known refractivity profile and an initial transmitted field. The …

Four approaches to underwater sound propagation modelling are reviewed including rays,
normal modes, Green's function integral, and parabolic equation. Specific programs are …

We consider a model initial and boundary value problem for a third-order partial differential
equation (PDE), a wide-angle “parabolic” equation frequently used in underwater acoustics …
