3D-printed hierarchical polymer metacomposites for microwave cloaking

该项目旨在开发一种用于微波隐身的复合复合材料，由使用3D打印技术的软铁磁性微丝组成。得到的轻质复合材料有望在复合材料细观结构的控制下具有梯度折射率，这有望通过自动化工程过程实现，而不涉及任何高成本的纳米制造过程。使用分级复合材料作为积木，可以制作一种微波斗篷，使其下面的任何物体对雷达探测等微波警戒设备都是看不见的。因此，拟议的复合材料在军事国防技术、航空航天和空间探索方面具有潜在的应用前景。

The project aims to develop a metacomposite for microwave cloaking, constituted by soft ferromagnetic microwires using a 3D printing technique. The resultant light weight composite is expected to have a gradient index with the control of composite mesostructure, which is expected to be possible with an automatic engineering process without involvement of any high-cost nanofabrication process. Using a graded metacomposite as a building block, a microwave cloak can be made that would make any objects beneath it invisible to microwave vigilant devices such as radar detection. The proposed metacomposite therefore has potential applications in military defence technology, aerospace and space exploration.
