Abstract

An approximate method is proposed for calculating the acoustic field produced by a finite-height cylindrical piezoceramic transducer with allowance for the radiation from the ends of its inner volume that is filled with an elastic medium characterized by an arbitrary Poisson’s ratio. Structural features of the transducer (the presence of a sealing compound and an inner baffle) are taken into account. Good agreement is obtained between calculations and experiment for two transducers (a short one with a height-to-radius ratio h/a≈1 and a long one with h/a≈3) whose inner cavities are filled with either water or foam plastic.
