Active metasurface in reflection manner for generation of reconfigurable OAM vortex beams

In this paper, we proposed an active metasurface in reflection manner that can generate reconfigurable OAM vortex beams with high purity in the X-band. The metasurface has a high reflectance of 0.94 and achieves a phase coverage of 320° between 9.8 GHz and 11 GHz. Then, by encoding the phase distr...
