P1E070-02. Acoustic Waves in LiNbO3/SiO2/Water/Silicon Rubber Structures

This paper studies acoustic waves in a water layer enclosed between the YZ-LiNbO3 substrate coated with a thin SiO2 layer and the half-infinite domain occupied by silicone rubber. The plane wave spectrum is computed. Numerical estimations are made of the COM-parameters describing a periodic grating deposited on the LiNbO3 substrate under the SiO2 layer. The dependence of the COM-parameters is investigated on characteristics and conditions specifying the structure.
