◎研究内容
Terahertz (THz) waves have drawn ever-increasing attraction in recent years due to their great potential in medicine identification, imaging, and wireless communications beyond 6G, etc. Arbitrary manipulation of THz waves is critical for developing THz technologies.
Metamaterial, as an artificial material consisting of periodic unit cells, can exhibit unexpected light-matter interaction that does not exist in natural materials by designing its structure and dimension, which is a remarkable scheme to regulate THz waves on demand. By properly designing the unit cell of metamaterials and using state-of-the-art micro/nano-machining technology, it is possible to achieve innovative manipulation of THz waves.
Microelectromechanical systems (MEMS) can convert electric energy to mechanical motion, thus, they can directly reconfigure the metamaterials to obtain a big tuning contrast of the manipulation. Additionally, MEMS are easy to be integrated into integrated circuits (ICs) for future miniaturized applications. MEMS-driven metamaterials offer an advantageous pathway to actively manipulate THz waves.
The time-variant metamaterials based on MEMS technology benefit advanced THz applications requiring high-performance modulations, such as high-resolution THz imaging and wireless communications.
