摘要
声子晶体的带隙特性、缺陷态特性和特殊的声学特性具有重要的应用价值。文章对声子晶体的基本概念和特征进行简要概述,总结了国内外声子晶在应用基础研究方面的成果以及国内有关声子晶体方面的专利发明情况,为深入声子晶体的应用研究提供依据。
The band-gap properties, characteristics of the defect states and acoustic features of phononic crystals are of great significance theoretically and practically. This article briefly summarizes the concept and features of phononic crystals and summarizes the achievements of phononic crystals＇ applied basis research both home and abroad and the patent inventions in China, thus it offers a basis for further research on the application of phononic crystals.
