Generation of Wideband Tunable Orbital Angular Momentum Vortex Waves Using Graphene Metamaterial Reflectarray
In this paper, a wideband tunable reflectarray consisting of a graphene-based metamaterial structure has been developed to generate an orbital angular momentum (OAM) vortex wave in terahertz. In the proposed reflectarray, a multi-layer graphene metamaterial unit cell is designed, and through varying...
