Research on Liquid Crystal-Integrated Metasurface Beam Deflector
A liquid crystal-integrated programmable metasurface beam deflector that exhibits a tunable deflection angle is designed,which combines a liquid crystal and Huygens resonant metasurface.Simulated results demonstrate that,compared with the same thickness liquid crystal,Huygens resonant metasurface increases the achievable range of phase control by a factor of~1.87.Furthermore,a 32-channel liquid crystal-integrated metasurface beam deflector is encoded using periodic and arbitrary coding methods,thereby achieving beam scanning with a field of view of 20° and providing a potential solution for solid-state beam scanning.
