▎ 摘　　要

The chiroptical response is ubiquitous and offers additional degrees of freedom in modern optics systems which require high efficiency and moderate modulation. Exhibiting a fascinating electromagnetic performance, a graphene-metamaterial hybrid structure is an ideal candidate to satisfy the requirements for chiroptical response. Herein, the interaction between a graphene layer and a multifunctional metamirror is investigated in the near-infrared region. The simulation results show that the graphene layer can moderately modulate the circular dichroism effect in the short wavelength region, while leaving cross-polarization conversion almost unaffected in the long wavelength region. This selective interaction can be well understood with the electromagnetic models and graphene surface conductivity. This work provides a guide for selectively modulating the multifunctional chiroptical response and presents a new strategy to detect the layers of graphene.
