摘要:
The velocities of microwave ultrasonic waves at 9.2 GHz have been measured using pulse‐echo techniques in X‐cut and Z‐cut quartz rods. In the X‐cut quartz, the longitudinal mode velocity was (5.71±0.05)×105cm/sec and the transverse mode velocities were (5.20±0.05)×105cm/sec. The longitudinal velocity for the Z‐cut quartz was (6.33±0.03)×105cm/sec. In contrast with the measurements of Ogawa and Sakamoto these results agree with the low—frequency velocities reported by McSkimin [J. Acoust. Soc. Am. 34, 1271 (1962)].
