摘要：
An analytic formulation for the transduction parameter required by the coupling-of-modes analysis of SAW transducers has been derived by comparing solutions obtained using the coupling-of-modes analysis and an equivalent quasi-static analysis using the method of Green's function. This work has resulted in the derivation of a convenient representation for the transduction strength of periodic SAW transducers. Using the formulation, analytic solutions have been obtained for the transduction magnitude and phase of regular SAW transducers. Nonregular transducers are also modeled with the help of an electrostatic field analysis of the transducer's structure.
