声波超材料是一种特殊的人工复合材料,它基于连续介质力学理论描述,通过对微观结构的精心设计,在宏观上获得反常规的动态材料属性,如负动态质量,负动态模量,负折射率等.超材料的出现为实现波动控制提供了可能,相关研究在工程领域具有潜在的应用价值.论文着重阐述了弹性固体超材料、声波超材料、超表面、主动超材料的设计原理与相关研究进展,所述原理对于波控结构的设计与制备实现具有指导意义.
Acoustic metamaterials are a kind of special artificial composite materials, which are described based on the theory of continuum mechanics. Through the careful design of microstructure, the abnormal dynamic properties of materials such as negative dynamic mass, negative dynamic modulus, negative Refractive index, etc. The emergence of metamaterials provides the possibility to realize the fluctuation control, and the related research has potential application value in the field of engineering.The dissertation focuses on the design principles of elastic solid metamaterials, sonic metamaterials, superlattices and active metamaterials, Related research progress, the principle for the wave control structure design and preparation of guidance.
