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