Emission of a metallic infrared emitter with hexagonal holes lattice structure

The unique emission of a metallic infrared (IR) emitter with hexagonal holes lattice structure has been reported in this paper. The emission spectrum of the IR emitter shows a strong narrow-band emission in middle infrared range. Though the positions of peaks of the emission and transmission spectra are almost coincide with each other, the transmission spectrum show sharper coupled effects than the emission spectrum and the strongest peak of the two spectrums is different. The coupled effect was analyzed in detail by the surface plasmon polaritons (SPPs) coupled dispersion model and the localized surface plasmon (LSP) theory. We found that the unique coupled effect is mainly depended on the excitation process of the LSP modes. The thermal image of the emitter shows that the substrate emission also has important interference in the emission spectrum.
