“…Absorbing materials are a class of functional materials that can effectively absorb electromagnetic waves and significantly reduce reflection. Traditional absorbing materials include ferrite [1], ultrafine metallic powder [2], polycrystalline iron fiber [3], plasma absorbing material [4], and so on. They can operate at various frequencies, such as microwaves, millimeter waves, terahertz, and infrared, and have been widely used in many fields.…”

We numerically investigated a dual-band metamaterial absorber based on the combination of plasmonic resonance and Fabry–Pérot (FP) resonance, which can achieve near-unity absorption for guided lasers. The absorber is constructed by a three-layer metal-insulator-metal (MIM) periodic configuration. In each unit cell, there is a gold-silicon cross on a thin silicon layer and a bottom nickel film. Numerical results show that, at normal incidence, the structure strongly absorbs light at wavelengths of 1.064 μm and 10.6 μm, with absorption rates higher than 94%. It is revealed that the two absorption peaks result from FP resonance in the thin silicon layer and plasmonic resonance in the cross, respectively. In addition, the absorber is polarization insensitive and is tolerant to the incident angle. The proposed combination of different resonances has the advantage of easily producing double absorption peaks with very large wavelength differences, and provides a new approach to the design of metamaterial absorbers.
