Abstract: “The frequency equation of the Rayleigh wave propagating in an anisotropic smart piezoelectric material is obtained. The non-dimensional velocity of the Rayleigh wave is computed for Barium Titanate. The surface mechanical displacements and electric fields are found as a function of layer thickness and are presented graphically. This theoretical work may be helpful in further experimental works on surface wave propagation in piezoelectric materials and surface acoustic wave filter devices.”
