The paper presents a novel design of a solar thermal absorber that utilizes graphene and three-layer constructions with titanium (Ti), iron (Fe), and ferric oxide (Fe₂O₃). The design aims to efficiently absorb solar heat and convert it into thermal energy for industrial applications. The three layers are structured as follows: Ti resonators, Fe substrate, and Fe₂O₃ ground layer. The addition of graphene between the Ti resonator and Fe substrate layers enhances absorption. The design is evaluated for absorption percentages in the UV, violet, near-infrared (NIR), and mid-infrared (MIR) regions, achieving high absorption rates. Specifically, the overall band of 2800 nm has a solar absorption rate of 90.25%, while the 1800 nm bandwidth shows 96.97% absorption and the 1000 nm bandwidth shows 97.84% absorption. The paper also discusses the polarization effects in TE and TM modes, electric field analysis, and a comparison table. The design's construction and parameters are detailed, including the use of COMSOL software and FEM techniques to simulate the radiation results.The paper presents a novel design of a solar thermal absorber that utilizes graphene and three-layer constructions with titanium (Ti), iron (Fe), and ferric oxide (Fe₂O₃).
