Effects of rotation and electric bias in the semi‐infinite piezoelectric medium on Rayleigh wave velocity

Abstract

AbstractThe properties of Rayleigh wave velocity are analyzed by considering the rotation and electric bias. The algebraic equation is derived for determining the piezoelectric Rayleigh wave velocity analytically and numerically for Lithium Niobate. The main results reveal that the rotation as well as electric bias has exerted an appreciable influence on the wave velocity. Particularly, the Coriolis force under the rotatory condition can decrease wave velocity considerably, and such attributes are significant for the acoustic electronics.
