Abstract
A multifrequency composite ultrasonic transducer system includes a transducer comprised of piezoelectric ceramic rods embedded in a polymer matrix. By selecting the appropriate thickness and width of ceramic rod, the transducer assembly can be made to resonate at a number of frequencies. One of the resonance frequencies is determined by the thickness of the ceramic rod; other resonance frequencies are determined by the width and/or the ratio of width to thickness of the ceramic rods.
