Abstract: Based on the finite element method, the interaction between cirular polarized lights and graphene metasurfaces is simulated, which shows the properities of the far-field and near-field responses of graphene metasurfaces. Results show that the plasmonic resonances are stimulated by circular polarized lights at the mid-infrared region. The absorption spectra are independent with the polarized direction of incident lights, which results in zero far-field chiral responses. However, the surface charge distributions, the local electric fields and the chiral near-fields are closely related to the polarized direction of incident lights. Through numerical simulation, the knowledges of cirular polarized lights and electromagnetism can be shown vividly, which should deepen students鈥� understanding and stimulate students鈥� creative consciousness.

Key words: circular polarized light, graphene, metasurface, chiral near-fields
