Abstract

The anisotropy of attenuation of acoustic waves in cubic bismuth germinate crystals has been investigated by Bragg diffraction of light method in frequency range 0.4 - 1.6 GHz. The effective imaginary elastic constants for acoustic waves along the crystallographic axes of symmetry were determined. It is shown that the highest anisotropy of attenuation is observed for piezoelectric acoustic waves in plane (001).
