Modelling acousto-elastic waveguide/object scattering with the Rayleigh hypothesis

Thumbnail
Abstract
In this memorandum the plane wave scattering matrices for a range-dependent seabed and upper free surface are computed using the
 
Rayleigh hypothesis at the interfaces. These matrices can then be used to compute the pressure field within a waveguide bounded by these surfaces; they can also be easily combined with the scattering matrix characterizing an object.
 
Computational examples are given for range-dependent acousto-elastic waveguides and the fields compared with those computed by other methods.
 
An example with a steel cylinder in the waveguide is also shown.
