Mode parabolic equations for the modeling of sound propagation in 3D-varying shallow water waveguides

2012 Proceedings of the International Conference Days on Diffraction, 2012
Mode parabolic equations (MPEs) developed in [1] provide a convenient tool for the modeling of waves propagation in 3D-varying environments. Application of the mode parabolic equations to the solution of the problems arising in shallow-water acoustics is discussed. The numerical method for the solution of the mode parabolic equations is developed.

The coupled mode parabolic equation

The Journal of the Acoustical Society of America, 1996
The coupled mode parabolic equation (PE) is a generalization of the adiabatic mode PE that includes mode coupling terms. It is practical to apply this approach to large-scale problems involving coupling of energy between both modes and azimuths.

Simulation of the pulse propagation by the interacting mode parabolic equation method

Computer Physics Communications, 2018
Abstract A broadband modeling of pulses has been performed by using the previously derived interacting mode parabolic equation through the Fourier synthesis. Test examples on the wedge with the angle 2.86 ∘ (known as the ASA benchmark) show excellent agreement with the source images method.
