Abstract
Equivalent circuit descriptions suitable for describing the impulse response of transducer systems are considered, and the suitability of the Mason circuit is demonstrated. This description leads to consideration of multilayer structures that are applicable to medical ultrasound transducers. Of several interesting structures, one formed by folding thin plastic piezoelectric materials is shown to have the possibility of uncreased coupling coefficient and reduced resonant frequency compared to the basic film material.
