Abstract :
A multiscale metamaterial stack consisting of a graphene sheet, a ferromagnetic nanowire membrane and a frequency selective surface is proposed and theoretically analyzed as an electrically tunable Faraday rotator. The magnetic bias is provided by the static field produced by the ferromagnetic nanowires and graphene is electrically biased through the frequency selective surface. The proposed tunable gyrotropic meta-material is electromagnetically transparent.
