- Abstract
We describe the effect of acoustical activity existing in TeO2 crystals under the condition of equal propagation velocities of the quasi-transverse and quasilongitudinal waves. Relations for the phase velocities and the ellipticities of eigenwaves are obtained. It is found that the eigenwaves excited by the quasilongitudinal wave and one of the quasi-transverse waves become circularly polarized. The difference of the phase velocities for these waves caused by the acoustical activity leads to a circular phase difference and also to rotation of the displacement vector with respect to the displacement vector that excites the acoustic wave.
