Abstract

A model of an ultrasonic pulse-echo system is presented which accounts for the finite beam width. The dependence of the spatial distribution of the reflected signal on the incident beam width is examined closely near the fundamental surface resonance frequency. Schoch type of displaced beam phenomena is predicted. Experimental data which were obtained using finite width transducers are presented, and compared to the corresponding theoretical predictions.
