Acoustic Reflection Analyzer for a Water-Sediment Interface

Application ID: 30881

Analyzing acoustic reflections at surfaces of various structures is important for many engineering disciplines. The Acoustic Reflection Analyzer for a Water-Sediment Interface app shows one such system where the analysis has relevance for underwater acoustics and sonar applications.

The app analyzes the reflection and absorption coefficients of plane acoustic waves, scattering off of a water-sediment interface at different frequencies and angles of incidence. Moreover, the random-incidence absorption coefficients are determined for the studied frequencies.

To describe the water-sediment system, the app uses the ability of the Poroelastic Waves interface in COMSOL Multiphysics to model the coupled acoustic and elastic waves in any porous substance (Biot's theory).

This application example illustrates applications of this type that would nominally be built using the following products:
