Abstract :
In this paper, we study propagation characteristics of surface acoustic wave (SAW) in structural array. We use focus ion beam (FIB) lithography as a fabrication process of structural array. We fabricated test devices with the structural array formed by metal deposition and etching by using the FIB process, respectively, in order to investigate SAW propagation. The experimental results show the stop-band characteristics and the pass-band characteristics. We try to clarify the feasibility of the SAW functional devices with the structural array, such as an opto-acoustic integrated device.
