Abstract

When the wave-vector matching criteria is satisfied, the incident light can excite the surface plasmon on the surface of the metallic micro-nano arrays, as to form the resonant surface electromagnetic field. From the perspective of surface charge rearrangement, we propose interfinger-type metal grating and cover the grating with graphene to manipulate the polarization response of light waves. By using FDTD software, we simulate the transmittance of the structure to the infrared light with different polarization angles, and analyze the local electric field distribution at the edge of the grating. According to the simulation results, the metal grating with graphene can manipulate the light wave transmission well, absorbing the polarization component parallel to the grating's long axis and passing through the polarization component perpendicular to the grating's long axis.
