Manipulation of the Faraday rotation by graphene metasurfaces

We demonstrate a simple structure including circular shape patterned graphene surface for manipulation of Faraday rotation phenomenon. The patterned structure can be utilized in the building blocks of vast tunable non-reciprocal components. The behavior of the structure is discussed analytically by circuit model approach and verified by numerical simulation. Obviously, manipulation of polarization rotation is attained from the circular shape pattern. Also, we show that Faraday rotation effect takes place at higher frequencies compared to the similar effect in uniform and un-patterned graphene.
