A method to extract the electromechanical couplig coecient k 2 t of the thickness extensional mode of a piezoelectric thin ยฎlm deposited on a substrate is presented, in which a two-layer structure is as a composite resonator. Based on the method proposed by Wang et al. (IEEE Trans. UFFC 46 (1999) 13
