### Abstract

Weak graphene plasmon is a key challenge for graphene-based metasurfaces in the visible and near-infrared regions. In this study, we have numerically designed and demonstrated a tunable, ultrathin, hybrid dual-band quarter-wave plate metasurface, which comprises of graphene, metal, and glass. Tunable birefringence has been obtained through the number of layers of graphene, its Fermi energy, metal dimensions, and the periodicity. The design also achieves a 95% polarization conversion ratio from a linear state to a circular state with a near unity value of ellipticity at a design wavelength in the near-infrared. The ultrathin thickness of the structure, 0.1 $$\lambda$$ λ , and an embedding glass makes the structure compact and easily integrable for photonic-sensing application in the near-infrared.
