Abstract

The KLM transmission-line model is used to analyze the performance of an ultrasonic transducer made from a composite piezoelectric material. The basic transducer parameters, including electrical and mechanical losses, are determined by analyzing the electrical impedance of the air-loaded composite disk in the vicinity of the thickness resonance. Using these parameters, the performance of a prototype 3 MHz composite transducer is calculated and found to be in good agreement with experimental data. On the basis of these results, the performance of the composite transducer with optimum acoustic and electrical matching is predicted. The results reveal substantial promise for composite piezoelectric materials in making efficient broadband ultrasonic transducers for medical imaging.
