Parameters affecting backscattered ultrasonic leaky-Rayleigh waves from liquid–solid interfaces

Experiments were carried out to observe backscattered ultrasonic waves from liquid–solid interfaces. It is found that the backscattered energy is maximum at the Rayleigh angle, directly proportional to the so-called Schoch displacement (Δs) and inversely proportional to the beamwidth. This result is...

Zusammenfassung:Experiments were carried out to observe backscattered ultrasonic waves from liquid–solid interfaces. It is found that the backscattered energy is maximum at the Rayleigh angle, directly proportional to the so-called Schoch displacement (Δs) and inversely proportional to the beamwidth. This result is in qualitative agreement with the Bertoni and Tamir [Appl. Phys. 2, 157–172 (1973)] theoretical prediction for the beam distortion of the reflected field at the Rayleigh angle. It is also suggested the backscattered phenomenon enables one to measure the Rayleigh velocity at liquid–solid interfaces.
