High-power piezoelectric ceramics are desirable to combine a high mechanical quality factor(Qm) with a high piezoelectricconstant(d 33) and a high planar coupling factor(Kp).
This paper is to display existence and its conditions to a surface acoustic wave propogating along surface of a half-body of piezoelectric ceramics with a rotation of constant angular velocity.
