Dynamic terahertz wavefront control using stretchable single-walled carbon nanotube-based metasurfaces‎

The terahertz (THz) frequency regime, sitting between microwaves and infrared light, has long promised revolutionary advances in wireless communication, security imaging and nondestructive sensing. A key roadblock, however, has been the lack of compact, dynamically tunable components capable of manipulating THz beams on demand.
