GYRO EFFECT ON SURFACE ACOUSTIC WAVE PROPAGATION IN A PIEZOELECTRIC LAYERED STRUCTURE
In this paper,we investigate the propagation of generalized Rayleigh waves in a piezoelectric layered structure.Considering the gyroscopic effect,and based on the theory of elastic dynamics,the field control equations with rotation are established.Substituting the trial solutions of the mechanical displacement and the electrical potential into the boundary and continuity conditions,we obtain the dispersion equation when the free surface is electrically open and electrically shorted,respectively.Numerical examples show that frequency varies approximately linear with the angular rate,and the change of frequency is more sensitive for long waves.The results provide a theoretical basis for designing SAW gyroscopes.
