Quasi-longitudinal pseudo-surface acoustic waves on lithium tantalate

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/spl deg/ to 30/spl deg/ with 10/spl deg/ step, the second and the third angles were changed in range from 0/spl deg/ to 180/...

More Information
Summary: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/spl deg/ to 30/spl deg/ with 10/spl deg/ step, the second and the third angles were changed in range from 0/spl deg/ to 180/spl deg/ with 5/spl deg/ 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.
