摘要
采用液晶和惠更斯共振超表面结合的方式,设计了一种偏转角度可调谐的液晶集成可编码超表面光束偏转器.数值仿真结果表明,惠更斯共振超表面将相同厚度的液晶能够实现的相位调控范围提高到～1.87倍.通过周期编码和任意编码两种方式对32通道的液晶集成超表面光束偏转器进行编码,实现了20°视场角的光束扫描,为固态光束扫描提供了一种技术方案.
Abstract
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.
