基于形状记忆机制的动态智能可调节吸波超材料设计及其性能调控研究

To solve the problem that the structure and performance of metamaterial absorbers cannot change, the applicant put forward a new idea to fabricate metamaterial absorber the structure and performance of which can be tuned smartly. The substrate of smart metamaterial absorber is made by shape memory polymer and the metamaterial unit-cell is made by liquid metal. The shape of metamaterial unit-cell can be change by shape memory effect of substrate and the performance of metamaterial absorber will be controlled reversibly. We will focus on the preparation method of SMP metamaterial absorber and the mechanism of shape controlling will be investigated also. At the same time, the mapping relationship between metamaterial unit-cell and microwave absorbing performance can be revealed. And eventually, this work will lay the theoretical and practical foundation for the smart controlling of performance of metamaterial absorbers.
