Abstract:Artificial metamaterials are man-made electromagnetic materials with subwavelength structure which demonstrate nearly-perfecet absorption performance at a designed resonance wavelength. Depending on their advantages, metamaterials are supposed to be a potential strategy to overcome the restrictions of the bulk infrared absorption materials, like the low absorption rate, large thickness, energy gap limitation. In this paper, we aim at realizing localized surface plasmon resonance based tunable dual-band absorber within 1-10 μm. We design a MIM structure, in which gold nanocubes are used to simulate the absorption properties of gold nanoparticels, and the calculated result are in good agreement with the experimental results. It is concluded that the high frequency absorption peak is contributed by F-P resonance, while the low frequency absorption peak is triggered by localized surface plasmon resonance. We have experimentally fabricated the large-scale dual-band absorber with the tunable absorption peaks by an annealing method.
