Abstract:

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
