超材料是指一类具有天然材料所不具备的超常物理性能的人工复合结构。超材料的出现为经典电磁理论开辟了新的研究方向，使电磁波的有效操纵成为可能。超材料最重要的应用之一是超材料吸收体。MMAs的性能取决于材料组成、电池尺寸和结构，通过合理的设计往往可以达到“完美”的吸收。本文从MMAs的发展和现状入手，重点介绍了仿生设计和新型人工设计。具体来说，就是从自然界的动植物中汲取灵感，设计新颖的结构来获得更好的吸收性能。此外，人工设计可以实现最佳的吸收容量和吸收带宽。此外，本文还对3D打印技术制备不同于传统印刷电路板技术的mma进行了综述。通过3D打印技术生产的mma可以制备更复杂的形状，并且具有重量轻和更好的吸收性能。(c) 2022年由Elsevier Ltd代表Journal of Materials Science & Technology编辑部出版。
Metamaterials refer to a class of artificial composite structures with supernormal physical properties that natural materials do not have. The emergence of metamaterials has opened up new research directions for classical electromagnetic theory and made it possible to manipulate electromagnetic waves effectively. One of most important applications of metamaterials is metamaterial absorbers (MMAs). The properties of MMAs depend on the material composition, cell size and structure, which could often achieve "perfect" absorption through reasonable design. This review starts with the development of MMAs and describes the status of this absorber, then mainly focuses on bionic design and new artificial design. Specifically, it is to draw inspiration from natural plants and animals, design novel structures to get better absorbing properties. Furthermore, the artificial design can achieve the optimize absorption capacity as well as absorption bandwidth. What's more, this review summarizes the 3D printing technology to prepare MMAs that are different from traditional printed circuit board technology. The MMAs produced by 3D printing technology can prepare more complex shapes, and has light weight and better absorbing properties.
