Design of a Visible Broadband Metamaterial Absorber Based on Nickel Metal

In this paper, we propose a visible broadband metamaterial absorber (MA) based on nickel metal. The MA is composed of three layers: a nickel-based pattern array on the top, silicon dioxide in the middle layer, and a nickel film at the bottom.

Description
Summary:In this paper, we propose a visible broadband metamaterial absorber (MA) based on nickel metal. The MA is composed of three layers: a nickel-based pattern array on the top, silicon dioxide in the middle layer, and a nickel film at the bottom. The performance of the MA was simulated by the finite-different time-domain method. The average absorption of the designed absorber reaches 95.76% in the whole visible spectrum of 380 – 750 nm. The absorption rates at 500 and 637 nm are 96.63% and 99.93%, respectively. In addition, the MA proposed is insensitive to polarization in the whole visible region. Then we investigate the mechanism of the high absorption rate and the influence of the structural parameters on the absorption spectrum. Propagating surface plasmon resonance and localized surface plasmon resonance are generated at resonant wavelengths of 500 and 637 nm, respectively. This is theoretically consistent with the parametric study. The proposed MA shows extensive application prospects, such as for solar cells.
