On the Electromechanical Coupling and Electrical Impedance of a Thin Piezoelectric Disk with an Arbitrary Impedance on the Boundary

摘要

Expressions are developed for the electrical impedance, resonant frequencies, and dynamic electromechanical coupling coefficient for an arbitrary impedance on the boundary of a thin piezoelectric disk. The equations are then specialized for the case of a spring-like boundary condition. (Author)
