Perfect Anomalous Reflection and Refraction Utilizing Binary Pancharatnam-Berry Phase Elements Based Metasurfaces
In this paper,a novel method is proposed to realize perfect anomalous reflection and refraction utilizing metasurface composed of binary Pancharatnam-Berry(P-B)phase elements.Previous studies on perfect anomalous reflection usually suffer from low efficiency and complicated calculations.In contrast,the proposed method,which combines the metagrating theory and array antenna theory together,use only two kinds of unit cell structures for both perfect anomalous reflected and refracted beams generation.As a proof-of-concept,two binary P-B phase elements based metasurfaces are designed and simulated to show that the incident wave can be reflected from θi=60° to θr=60° for the perfect anomalous reflective metasurface,while the incident wave can be refracted from θi=60° to θt=60° for the anomalous refractive metasurface.The simulated results show good accordance with our theoretical predictions,indicating the anomalous reflection and refraction can be realized with high efficiency.Our method may open a new route in manipulating the propagation of the electromagnetic wave.
