摘要	In this paper, a rigorous numerical simulation method(FDTD) is employed to study the grating diffractive behavior of surface plasmon polariton(SPP) waves on meta-surface excited by the incident visible light through metallic grating coupler in 550-700 nm waveband. The simulation results indicate that the diffraction of SPP waves on meta-surface is quite different from that of free space light. Due to the near-field characteristics, the SPP wave shows obvious diffractive effect in near field when it interacts with a metallic grating. However, the different diffracted orders will merge into one after propagating some distances. Nevertheless, the diffractive behavior in near-field is similar to that in free space. In near field, only the 0th order light is transmitted when metallic gratings have a sub-wavelength period and higher diffraction orders appear when the period of metallic gratings is larger than the wavelength of SPP waves. The research results of this paper are of great significance for designing spectroscopic devices or systems on meta-surface with a micronscale. 2018, China Science Publishing & Media LTD.
