摘要:
Schoch has pointed out that an ultrasonic beam incident on a liquid‐solid interface is displaced appreciably when the angle of incidence is such that Rayleigh surface waves are generated on the interface. This theory has been extended by Brekhovskikh. Examination of the reflected beam near this angle using a precision goniometer reveals that the energy is redistributed into multiple beams, one of which may be dominant. Experimental results obtained with a Gaussian amplitude distribution across the incident beam are discussed. [Research supported by the Office of Naval Research.]
