Underwater Ray Tracing in a 2D Axisymmetric Geometry

Application ID: 44711

When computing ray intensity in 2D axisymmetric models, the wavefront associated with the propagating ray is treated as a spherical or ellipsoidal wave, instead of a cylindrical wave. This tutorial example illustrates how to set up several important features using the Ray Acoustics interface. It illustrates the intensity and phase calculation in graded media (speed of sound profile) including frequency-dependent attenuation in seawater (using a semiempirical model from literature). Two different boundary reflection models are used for the sea surface and the sea bottom.

All material properties and reflection models can be analytical functions or imported model data. They can depend on frequency and angle of incidence.

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