Piezoelectric Transducer Materials and Techniques for Ultrasonic Devices Operating above 100 MHz

Abstract

In the field of ultrasonics, the frequency range above 100 MHz was until a few years ago largely the province of research scientists concerned with studies of acoustic losses in solids. However, this frequency range has since become important for engineers concerned with certain ultrasonic devices such as dispersive and nondispersive ultrasonic delay lines, ultrasonic light deflectors, and ultrasonic light modulation devices. There are already in existence practical ultrasonic delay lines(1) for the storage of digital data signals at bit rates as high as 100 Mbits/sec. Similarly, light modulators(2) and light deflectors(3,4) operating at frequencies of several hundred MHz have been built and light modulators, light deflectors, and delay lines requiring total 3 dB bandwidths of several hundred MHz are within the reach of existing technological capabilities.
