The possibilities of forming narrow, weakly divergent ultrasonic beams by means of various types of piezoelectric transducers are analyzed. Special attention is given to transducers that have a nonuniform distribution of acoustic pressure from the radiating surface. It is shown that transducers for which this distribution has the form of a Bessel function J/sub 0/ will produce narrow, weakly divergent ultrasonic beams in both the near and far zones.
