The finite element technique is applied to a problem of composite piezoelectric transducers for ultrasonic radiation. Their characteristics, input admittances at the electrical terminals, the loading effect of acoustic radiation, near-field sound pressure distributions, and directional patterns are analyzed. In our previous work, two computer programs were separately developed to predict the behavior of piezoelectric resonators and acoustic transmission-radiation systems. These are now combined… CONTINUE READING
