Summary: | Metamaterials aim to recognize and emphasize their impact on multiple applications, and the objective of this study is to achieve higher performance of metamaterial solar absorbers for thermal management during winter and summer seasons. This paper outlines the metamaterial design strategy using low-cost materials, with its essence being the exploitation of the unique properties of the metamaterial to extend the composite performance of transparent planar solar absorbers. We designed a transparent multilayer planar absorber coating by using Iron Sesquioxide (Fe2O3) as the dielectric spacer and Titanium (Ti) metal for ground and resonator metal layers with both the cladding made of Silicon dioxide (SiO2) within thin resin film. The proposed MIM design affirms the presence of the negative refraction property of light, a unique property for metamaterials, Additionally, it can be used to retain sufficient energy during absorption which will enhance winter thermal management in buildings for angles of incident θ < 50° and the same setup accessed at θ > 50° will highly reflect the energy and will maintain the low temperatures in a given room during the summer season. |
