Abstract:
The selectivity of absorption spectrum by using surface plasmonics have attracted more and more research attentions. In this paper, the periodical surface plasmonic nanostructures were presented, which consist of metal nanostructures on metallic substrate, to enhance absorption rate of ultra-high temperature metal nanostructures. The characteristics of materials' absorption have been simulated and analyzed by changing different parameters in the range of wavelength 200-4000 nm. The simulation results indicate that there always appear absorption peaks and they reach over 93% at absorption spectrum with all different parameters. The dielectric material, period, depth and size of nanostructure are the main factors for the absorption spectrum. Further, the dielectric material and period of nanostructure also have obvious selectivity characteristics on the position of absorption peak. The study results can provide theoretical foundation for ultra-high temperature surface plasmonic materials absorption characteristics.
