Light Beam Steering Demonstration by Using Liquid Crystal Loaded Metasurface

We proposed two types of LC-loaded metasurface devices having a simple cuboid and a cuboid with a chevron-waveguide structure as a unit cell and showed simulation results on light beam steering. According to the results, it has been confirmed numerically that the light steers at the metasurface devices and its angle can be controlled by change of refractive index. By employing the cuboid with a chevron-waveguide structure, the same steering angle was achieved at lower refractive index change.
