Abstract
A leaky surface acoustic wave transducer operating at a liquid-solid boundary radiates a longitudinal wave into water. The structure of aPVDF/ interdigital transducer/fused quartz plate is analyzed numerically to understand the transducer performance including the phase velocity and efficiency for the acoustic beam radiation into water in comparison with the characteristics in a structure incorporating a piezoelectric ceramic plate instead of PVDF. The zeroth-order mode has a large transducer efficiency, although the electromechanical coupling constant is small. The results are useful in designing an ultrasonic transducer for acoustical imaging and sensor technology.
