声子晶体的能带结构和潜在应用

Band Structure and Potential Applications of Phononic Crystals

声子晶体是近10年来提出的一种具有声子能带和带隙的新型声学功能材料，它具有奇特的调节声子传播状态的特性。综述了声子晶体的能带结构和潜在的应用。

Phononic crystal is a novel type of acoustic functional materials having phononic bandgap before ten years. It exhibits a peculiar characteristic that can modulate the transmitting state of the phonon. This paper introdues its phononic band structure and potential applications.
