Abstract

The PZT fiber composites were investigated to determine the effect of various volume fractions and passive backings on high frequency response. Parylene C was shown to be an effective matching layer for these composites, improving bandwidth of the 30% volume fraction transducers by 20% and sensitivity by 5 dB. Finally, a test setup, taking advantage of state of the art in linear positioners, is presented.
