摘要
研究了声波在二维声子带隙材料中的传输特性 ,把声子带隙材料作为一个散射体进行处理 .在远场近似下 (kr 1) ,计算了声波在有限范围内声子带隙材料中的传输系数 。
In this paper, we study transmissive property of acoustic wave in the two dimensional phonon band gap material(PBG).In the far field, we treat PBG samples as scattering objects and calculate transmission coefficient of acoustic wave in the finite-sized phonon band gap materials,the calculated resulted agree well with the band structure.
