N2 - In this work, broadband and ultrathin graphenebased polarization converters operating at terahertz (THz) frequencies are designed and presented. The cross-polarization converter is constituted by a periodic L-shaped patterned graphene monolayer placed on a dielectric spacer layer and terminated by a gold substrate. This subwavelength design can convert linearly polarized waves to their cross polarized version operating in reflection. Next, a circular polarization converter is presented operating in transmission, which is based on arrays of rectangular graphene patches positioned over a thin dielectric substrate. This THz design can convert the linear polarized incident wave to circular or elliptical polarized transmitted radiation. Both polarization converters are ultrathin and work over a broad frequency range and for different incident angles. In addition, they have tunable responses and are envisioned to become the building blocks of future integrated THz systems.
