弹性波在声子晶体中的带结构

Relation of Phonon Crystal Band Structure of Elastic Waves in Phonon Crystal

本文用平面波方法,研究了Pb圆柱体在epoxy基体中按周期性排列时的弹性波带结构,研究发现弹性波在将质量密度较大的介质柱嵌入质量密度较小的基体构成的声子晶体中将有完全带隙出现.

In this paper, using the plane-waves method, We study the elastic waves band structure of Pb cylinders embedded in epoxy with periodic array, and find complete band gap of elastic wave in phonon crystal as high-density inclusions in low-density host.
