报告简介：

A mode parabolic equation method for resonantly interacting modes has been developed. The method ensures acoustic energy flux conservation in accord with multiple scaled analysis accuracy. We carried out testing calculations for the ASA wedge benchmark, that showed excellent agreement with the COUPLE program.  A broadband modeling of pulses has been performed by using the derived interacting mode parabolic equation through the Fourier synthesis. Test examples on the wedge with the angle 2.86 degree (known as the ASA benchmark) show excellent agreement with the source images method.
