Dynamic control of terahertz (THz) waves at will with an ultra-compact device is important for THz technologies in biomedical imaging, telecommunications, detection, and beyond. However, tunable THz devices made of conventional materials are usually bulky, and they tend to have limited modulation depths and functionalities, due to weak interactions between naturally existing materials and THz waves. Metasurfaces--functional materials endowed with unparalleled flexibility to manipulate light at t...
