摘要

This paper investigates influence of coupling between Rayleigh and SH SAWs on rotated Y-cut LiNbO3 to their electromechanical coupling. For the purpose, a COM model including the coupling between two SAWs is developed, and its validity is confirmed by comparison of its results with the FEM analysis. Then it is discussed how the coupling influences to their excitation in addition to propagation. After that, variation of COM parameters is discussed with the device design.
