Abstract
Velocities and attenuations of piezoelectric leaky surface waves in LiNbO3 are computed. As the result, we have found that the effective electromechanical coupling coefficient of the leaky surface wave propagating along the x axis of the 64° rotated y‐cut plane is very large, K2=0.113; and by radiating the energy into the solid this wave attenuation is 0.36 dB/wave‐length for the free surface and goes to zero for the metalized surface.Keywords
