The invention discloses a graphene metasurface used for spin angular momentum deflection in a two-dimensional direction. The graphene metasurface is formed by arranging N * N graphene reflection units, and each graphene reflection unit comprises a graphene sticker at the uppermost layer, a quartz dielectric plate at the middle layer and a metal floor at the bottom layer, wherein the graphene sticker is arranged at the central point of the upper surface of the quartz dielectric plate. The rotation angle of each graphene sticker arranged on the upper surface of the quartz dielectric plate is theta, the metal floor is arranged on the lower surface of the quartz dielectric plate, and the central point of each graphene sticker coincides with the central point of the quartz dielectric plate, wherein the theta is an any angle ranging from -90 degrees to 90 degrees. The rotation angle theta of the graphene sticker of each graphene unit arranged on the upper surface of the quartz dielectric plate is determined by the reflection phase distribution at each position of the graphene metasurface. According to the invention, the spin angular momentum and the deflection direction of electromagnetic waves in the two-dimensional direction can be controlled.
