Applications of metasurfaces for OAM wireless communication

Caption

Figure 3. Several typical applications of metasurfaces for OAM wireless communication: (a) and (b) OAM beam generation using scattering programmable metasurfaces, with schematic diagram and unit structure. (c) and (d) Programmable millimeter-wave metasurfaces for dynamic OAM beam generation, with schematic diagram and metasurface unit structure. (e) and (f) Programmable metasurfaces for simultaneous transmission of multi-mode OAM beams, with schematic diagram and unit structure. (g) and (h) Metasurfaces generating four-channel vortex beams using circularly polarized light, with schematic diagram and metasurface unit structure.
