已经使用3D打印构造了声学超材料。它包含一系列充气通道，其大小和形状可以在设计和制造过程中变化。在本文中，我们分析了数值和实验的这种聚合物超材料结构的特性，并证明了其用于在可听频率范围内的亚波长尺寸的样品的成像。(C)2016年作者。除非另有说明，否则所有文章内容均根据知识共享署名（CC BY）许可证（http：//creativecommons.org/licenses/by/4.0/）进行许可。
An acoustic metamaterial has been constructed using 3D printing. It contained an array of air-filled channels, whose size and shape could be varied within the design and manufacture process. In this paper we analyze both numerically and experimentally the properties of this polymer metamaterial structure, and demonstrate its use for the imaging of a sample with sub-wavelength dimensions in the audible frequency range.
