SPICE model for lossy piezoceramic transducers

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1997
A transmission line equivalent circuit for piezoelectric transducers has been modified to provide modeling of lossy piezoceramic transducers. A lossy transmission line is used to model the mechanical losses. The equivalent circuit parameters are derived from analogies between electrical transmission lines and acoustic wave propagation.
