▎ 摘　　要

We demonstrate the transformation of an oblique illumination into dual split beams with coplanar and non-coplanar anomalous reflections using checkerboard graphene meta-surfaces. Especially, the split beams generating from the interlaced two different graphene meta-atom arrays would be capable of maintaining the polarization states highly consistent to the incidence. In addition, such checkerboard graphene meta-surfaces can readily assign the intensities dynamically of the deflected dual beams with controllable scattering directions through simply resetting the Fermi energy of the meta-atoms array. The proposed design scheme, using checkerboard graphene meta-surfaces to generate split anomalous reflections in different planes simultaneously, should pave the way for tangible applications of three-dimensional wave manipulations.
