摘要

用有限元方法计算了一维杆状声子晶体的振动传输特性及其振动模态，从振形角度分析了一维杆状声子晶体相关参数（物理参数、尺寸参数）对带隙起始频率及带隙宽度的影响，发现带隙的形成与其模态振形密切相关，各参数对声子晶体带隙的影响主要是影响了个模态所在的频率，从而改变了其带隙的起始位置及宽度。

Abstract

Calculated vibration transmission property and vibration mode of one dimension rod photonic crystal by FEM, from vibration form Angle to study effect of related parameters(physical parameters, size parameters) to gap's starting frequency and band gap width. Found the band gap is closely related to the modal shape, the influence of these parameters to the band gap is mainly influenced modal frequency, change the band gap starting position and width.
