摘要:
The frequency dependence of the attenuation of acoustic waves in zinc oxide at microwave frequencies was measured using light‐scattering techniques. For a longitudinal wave propagating along thecaxis af2dependence was found and for a shear wave perpendicular to thecaxis the frequency dependence was notf2; the most probable reason being the presence of scattering centers in the crystal.
