摘要
声子晶体是近年来提出的一种新型功能材料,目前主要处于理论研究阶段。通过与光子晶体类比,可推断由振动材料组成的周期性结构,传输弹性波时也有带隙存在,这种特征可以有效地进行声波控制和振动控制,阐述了声子晶体的概念、基本特征、研究方法和进展。
Phononic crystal is a novel type of acoustic function materials which is presented near years. Now it is studied only theoretically. From the analogy between photonic crystal and phononic crystal, we may infer the existence of phononic band gaps of elastic waves in periodic elastic composites of vibrating materials. This basic feature will offer us some ways in vibration and sound control. This paper mainly discusses the concepts, basic features, calculating methods and development of phononic crystals.
