Abstract

We propose a numerical study of the three-layered Tungston-MgF2-Gold-based ultrawideband metamaterial absorber for the infrared wavelength spectrum. The behaviour of the metamaterial absorber is investigated for the infrared wavelength range of 0.25 to 3 μm. The absorber's behaviour is examined under various physical conditions to determine the best possible outcomes and structural dimensions. This structure may trap more than 98% of the near-infrared and visible light spectrums. Far-infrared and THz spectral absorption are both well-served by the proposed structure. This proposed infrared absorber design can be used for designing a high-efficiency solar cell.
