Abstract
The propagation characteristics of surface acoustic waves (SAWs) and piezoelectric leaky surface waves in single crystal KNbO/sub 3/ were investigated theoretically and experimentally. The results show that the electromechanical coupling coefficient of the surface wave propagating along the X-axis of the rotated Y-cut plane is very large, K/sup 2/=0.53, compared to K/sup 2/ of 0.055 for LiNbO/sub 3/.
