An improved interpretation of Mason´s model for piezoelectric plate transducers

A new interpretation of Mason??s model (1948) for a piezoelectric plate transducer is presented. The network model emphasizes a series connection for the two acoustic loads while utilizing lumped impedance elements expressed 88 functions of the delay operator Z = exp ST. An exact analysis of the plate dynamics permits a simplifii resistive model for conditions of light asymmetry in acoustic loading. A simplified resistive structure provides transmission (reception) loss near the halfwave resonance. Air backed front loading b modeled. Finally, RLC lumped component models are provided fo1 evaluation of transducers as lumped-element filters.
