摘要
通过将双层柱状微结构加工在SAW芯片表面,在COMSOL有限元仿真软件下实现了声波在结构内部的单点聚焦以及多极局域效应,并得出了结构尺寸与声波频率的对应关系.
By machining double-column micro-structures on the surface of SAW chip,single-point focusing and multi-pole localization effects of acoustic waves within the structure were achieved under COMSOL finite element simulation software,and the corresponding relationship between structure size and acoustic frequency was obtained.
