Theoretical prediction of a backscattering maximum at Rayleigh angle incidence for a smooth liquid-solid interface

A numerical integration method for the description of acoustic bounded beams is used to calculate possible backscattering strength from a smooth liquid–solid interface. It is shown that the backscattering strength is maximum for Rayleigh angle incidence. The influence of beam shape and beamwidth on...

Beschreibung
Zusammenfassung:	A numerical integration method for the description of acoustic bounded beams is used to calculate possible backscattering strength from a smooth liquid–solid interface. It is shown that the backscattering strength is maximum for Rayleigh angle incidence. The influence of beam shape and beamwidth on the backscattering strength near the maximum is demonstrated.
