Abstract :
The polarization properties of magnetically biased graphene are investigated. It is shown that graphene rotates the polarization of a perpendicularly incident linearly polarized plane wave. The rotation angle dependence on the chemical potential and on the magnetic bias field is analyzed. Substantial rotation is found to exist in an extremely large microwave frequencies range. A new circular waveguide graphene Faraday rotator with enhanced bandwidth and thermal characteristics is proposed.
