Abstract :
Quantitative experimental results of the effect of surface and crystalline quality on acoustic-surface-wave attenuation on yz lithium niobate are presented. All data were taken at room temperature and at approximately 1.9 GHz. Surface roughness of the order of 0.25 wavelength causes an approximately 50% increase in the surface-wave attenuation.
