Abstract :
Calculations of quasi-longitudinal pseudo-surface acoustic waves for all the Euler angles on lithium tantalate are performed. The first Euler angle was changed in range from 0° to 30° with 10° step, the second and the third angles were changed in range from 0° to 180° with 5° step. It was found that quasi-longitudinal pseudo-surface acoustic waves exist in many ranges of Euler angles. All these ranges are shown in two-dimensional contour maps. Ranges of Euler angles, corresponding to relatively good propagation characteristics, are shown in detail.
