Multichannel terahertz quasi-perfect vortex beams generation enabled by multifunctional metasurfaces

Multichannel terahertz quasi-perfect vortex beams generation enabled by multifunctional metasurfaces

Vortex beams carrying orbital angular momentum (OAM) open a new perspective in various terahertz research. Multichannel and divergence controllable terahertz vortex beam generation holds the key to promoting the development of OAM related terahertz research. Here, we introduced and experimentally de...
