英文摘要	a gradient permittivity meta-structure (gpms) model and its application in super-resolution imaging were proposed and discussed in this work. the proposed gpms consists of alternate metallic and dielectric films with a gradient permittivity which can support surface plasmons (sps) standing wave interference patterns with a super resolution. by employing the rigorous numerical fdtd simulation method, the gpms was carefully simulated to find that the period of the sps interference pattern is only 84 nm for a 532 nm incident light. furthermore, the potential application of the gpms for wide-field super-resolution imaging was also discussed and the simulation results show that an imaging resolution of sub-45 nm can be achieved based on the plasmonic structure illumination microscopic method, which means a 5.3-fold improvement on resolution has been achieved in comparison with conventional epifluorescence microscopy. moreover, besides the super-resolution imaging application, the proposed gpms model can also be applied for nanolithography and other areas where super resolution patterns are needed.
