Abstract:
An ultrasonic resonator for measuring sound velocity in soft materials over a wide frequency range is designed and constructed, with special attention paid to the thickness matching and parallelism between transmitting and receiving transducers. The resonator is composed of x -cut quartz disks and has shown a very sharp spectrum in the frequency range of 3 to 200 MHz with practical signal strength. As an exemplifying data, the sound velocity change in the process of gelation of a chemical gel is presented. The possibility of a composite cavity which is operational over three decades of the MHz range is discussed.
