Deflective Vortex Beam Generation Based on Metasurfaces in the Terahertz Band

Terahertz vortex beams can be used to improve the communication capacity of radar communication systems and the resolution of imaging systems. This paper presents a deflective vortex beam generation method based on a reflective metasurface working in the terahertz band. Without the limitations of tr...
