Abstract

This work presents the designs of tunable mid-infrared (MIR) beam steering devices based on multilayer graphene-dielectric metamaterials. A tunable beam steering is achieved by changing the chemical potential of each graphene layer and, therefore, the effective refractive index of the metamaterial. Three different beam steerer concepts with a wide range of output angles (up to approximately 70°) are discussed. The proposed graphene-based tunable beam steering can be used in tunable transmitter/receiver modules for infrared imaging and sensing.

用于光束导向的石墨烯介电超材料
本文提出了基于多层石墨烯-介电材料的可调谐中红外光束导向装置的设计。通过改变每个石墨烯层的化学势,从而改变超材料的有效折射率,可以实现可调谐的光束导向。三种不同的光束转向概念与宽范围的输出角度(高达约70°)进行了讨论。所提出的基于石墨烯的可调谐波束转向可用于红外成像和传感的可调谐发射/接收模块。
