Abstract
Poly(vinylidene fluoride) (PVDF) transducers are well suited for use in high frequency pulse-echo ultrasound systems because of their high bandwidth. We analyze the design parameters of PVDF transducers operating in the 100 MHz range using the KLM transducer model. The effect of backing layers, electrode configuration, transducer surface area and tuning circuits on the insertion loss and pulse-echo response of the transducers are investigated. Using this design procedure, an experimental PVDF transducer is proposed for applications in the 100 MHz range. The transducer is built into a high frequency SMA electrical connector. Insertion loss and pulse-echo response measurements are compared with theoretical predictions.
