3D-printed hierarchical polymer metacomposites for microwave cloaking

该项目旨在开发一种用于微波隐身的超复合材料，该复合材料由软铁磁微线组成，采用3D打印技术。由此产生的轻质复合材料有望在复合材料介观结构控制下具有梯度指数，这有望在不涉及任何高成本纳米制造过程的自动化工程过程中实现。使用一种渐变的超复合材料作为构建块，可以制造出一种微波斗篷，使其下的任何物体对雷达探测等微波警戒设备都不可见。因此，所提出的超复合材料在军事防御技术、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.
