Analysis of Broadband Piezoelectric Transducers by Discrete Time Model

Abstract

The simulations of a discrete time model of the impulse response of
matched and backed piezoelectric transducers have been used to design
sensitive short-response transducers. The effect of matching and backing
materials layers on the performance of piezoelectric transducers working into
water load is investigated. The optimum acoustical characteristics of the
quarter-wave length matching layers are determined relatively to a
compromise between the sensitivity and the bandwidth.
