摘要

声学超材料是指具有等效负质量密度和负体积模量等超常声学性质的一种复合材料,典型的声学超材料通常由特定的结构而非材料组成来达到其特性,目前已成为声学领域研究的热点。其中,薄膜型声学超材料是当前研究广泛的一种超材料,具有较好的声学性能。本文介绍了薄膜型声学超材料近几年来的研究进展,包括负等效声学参数薄膜型声学超材料的实现方法及思路,结尾对薄膜型声学超材料的研究做了总结和展望。
Acoustic metamaterials are fabricated materials which have extraordinary acoustic properties of negative effective mass density and effective modulus. The typical acoustic metamaterial usually consists of a specific structure rather than the material to achieve its features, which has become a hotspot in the field of acoustic. Among them, the membrane-type acoustic metamaterials having a good acoustic performance are widely researched in the present study. In this paper, research progress of membrane-type acoustic metamaterials in recent years is introduced, including the realization methods and methods of the negative effective acoustic parameters. Finally, a summarization of membranetype acoustic metamaterials is given.
