Gyroscopic effect on surface waves in piezoelectrics

Abstract

This paper represents an analysis of surface waves propagating in rotating piezoelectric solids. The analysis shows that the effect of rotation on wave speed may be of first- or second-order of the rotation rate, depending on the propagation direction and the orientation of the material. For certain materials there exist two surface waves corresponding to the Rayleigh wave and the Bleustein-Gulyaev wave. For some other materials there exists one surface wave only.
