摘要
A direct method to characterize a piezoelectric film has been developed. Based on the measured resonance spectrum of a composite resonator, the electromechanical coupling coefficient k(t)(2), density and elastic constant C-33(D) Of the piezoelectric film can be derived. Good agreement with experiment was obtained.
