Acoustic waves on liquid crystal: elastic body boundary

The acoustic waves on the interface surface between elastic medium and liquid crystal (LC) were examined. When the elastic body is Bi12SiO20 and liquid crystal is smectic A (DEADB) then Rayleigh type and leaky waves are present in the considered case. For leaky waves final results are similar to those reported for Langmuir-Blodget films. Calculations were made in the case without dispersion of elasticity in liquid crystal medium.
