英文摘要

This paper investigated the cavity characteristics analysis of the two-dimensional phononic crystal Present phononic crystal is composed of steel cylindrical with square array embedded in air background. The plane wave expansion method and supercell calculation are adopted to obtain the band structures and transmission characteristics of the perfect and defect modes of the phononic crystal. Additionally, the COMSOL Multiphysics software is used to simulate the acoustic wave propagation in the PCs with a point defect.
