| Abstract(in English) | When liquid is loaded on the surface of the piezoelectric substrate along which the surface acoustic wave propagates, the surface acoustic wave becomes leaky surface acoustic wave, because the energy of the surface acoustic wave is transferred from the substrate to the liquid. Recently, crystalline LiNbO_3 can be grown on the sapphire substrate, and this layered-substrate is expected to be used for high frequency devices. In this paper, phase velocity, propagation loss, electro-mechanical coupling coefficient, and particle displacement distribution of the leaky surface acoustic waves propagating along Liquid/LiNbO_3/Sapphire structures are numerically calculated. As a result, it is found that the LiNbO_3/Sapphire substrate is suitable for the liquid sensor. |
