Surface and Shallow Bulk Acoustic Waves Propagating on Doubly Rotated Quartz Substrates.

Abstract

Doubly rotated cut quartz possesses many desirable features for acoustic wave devices. In addition to its excellent temperature behavior, it nonlinear elasticity produces mechanical and thermal stress-compensating effects. Doubly rotated cuts of quartz have been extensively used to construct bulk wave resonators for frequency-stable sources. In this report we will describe the acoustic properties of Surface Acoustic Waves (SAW) and Shallow Bulk Acoustic Waves (SBAW) on doubly rotated quartz. A number of delay lines have been constructed on various doubly rotated cuts of quartz. The frequency response of SAW is similar to that obtained on ST-cut quartz. The three SBAW modes predicted from theory were also observed. Both theoretical and experimental results are presented. (Author)
