【摘要】 针对随机失谐的声带隙复合介质中平面波的传播和局部化问题进行了研究。引入势函数求解了波动方程,采用传递矩阵方法计算了波传播的局部化因子,分析了入射角对波动局部化的影响和波的全反射现象。更多还原

【Abstract】 Propagation and localization of plane waves in randomly disordered acoustic bandgap media are studied in this paper.The localization factor is calculated by the transfer matrix method.Incident angle is changed to analyze the wave propagation and localization in the media. And total reflection of the wave is also studied in this paper.更多还原
