| Abstract(in English) | In this paper, we study basic propagating characteristics of Surface Acoustic Wave (SAW) in the two dimensional periodic structure for realizing a small size and high-functional device. In periodic array as a sonic crystal or a photonic crystal, the waves have many attractive characteristics of propagation such as a stop band, a pass band and wave guide. In order to realize these characteristics of wave propagation in the two dimensional periodic structure with small size, a larger difference of acoustic impedance between material that form a two dimensional periodic structure is required. As a basic study, we fabricated various two dimensional periodic structure such as wave guide, discontinuity and continuity area on the LiNbO_3 substrate. We investigated the frequency characteristics and waveguide effect of SAW in the two dimensional periodic structure. Experimental results indicated that pass band and two dimensional direction of SAW propagation would be applied to fabricate the devices such as filtering and switching. |
