Abstract

This paper investigates suppression of Lamb waves in piezoelectric composite transducers by matching their frequency to the even harmonics of the device thickness mode. This was done by a combination of experimental measurement on a number of transducers along with simulations using the finite element code PzFlex. Both 2-2 and 1-3 composites made from the single crystal materials pzn-4.5%pt and pzn-8%pt were investigated along with composites made from pzt5h ceramic. The theory is supported by means of experimental impedance analysis and laser scanning of surface displacement, with good agreement demonstrated.
