Fig. 3: Simulated results of graphene-based meta-device.
From: Dynamic manipulation of microwave polarization based on anisotropic graphene meta-device

Simulated reflected amplitude (a, b) and phase spectra (d, e) of the metasurface with a different sheet resistance of graphene under x- and y-polarized incident waves. Simulated amplitude (c) and phase difference (f) spectra as a function of sheet graphene's resistance. g The intensity spectra of the reflected electric field. h The tunable polarization angle for sheet graphene's resistance. i Simulated amplitude and phase response of the proposed meta-device without graphene layer.
