Abstract
A transmission line equivalent circuit for piezoelectric transducers h as been modified to provide modeling of lossy piezoceramic transducers . A lossy transmission line is used to model the mechanical losses. Th e equivalent circuit parameters are derived from analogies between ele ctrical transmission lines and acoustic wave propagation. Implementati on of the equivalent circuit model in SPICE is shown. Simulations and measurements in the time and frequency domain of a low-Q material and a multilayered ultrasonic sensor using a low-Q piezoceramic transducer are presented.
