Abstract
Manipulation of thermal radiation on metal materials attracted tremendous amount attentions in the past decades. In this study, we successfully designed simulated and manufactured three kinds of periodic micro-patterns on the nickel surface and realized the manipulation of the radiation spectrum and the polarization of nickel. The patterns which were applied to excite the surface plasmons were manufactured by the advanced ultrafast laser micro-machining technique. The experimental results of the thermal radiation showed good agreement with the simulation results. This low cost and designable method could pave the way for the future infrared applications.
