Abstract :
The existence of a new suppression cut to the most obstructive spurious component consisting of the slower shear wave propagatating in a crystal has been experimentally found out for acousticsurface-wave propagation on LiNbO3. The plate is a 127.86° rotated Y-cut X-propagating plate and has a large electromechanical coupling coefficient.
