Energy Harvesting and Electromagnetic Absorption Performance in Metamaterial-based Symmetric Ring Resonators: Effects of Resistance and Substrate Material
Year: 2025
Type: article
Abstract: This study aims to evaluate the effects of the symmetric ring resonator (SRR) structure on energy harvesting and electromagnetic absorption performance. The study consists of two phases: In the first phase, the impact of resistance values used in the SRR structure on energy harvesting and electromagnetic absorption rates was investigated. Simulations conducted with various resistance combinations demonstrated that energy harvesting performance could be optimized. In the second phase, the properties of the substrate material were analyzed in detail. Three different substrate materials were used with varying loss tangent values, revealing that the loss tangent property significantly affects energy harvesting and electromagnetic absorption performance. Moreover, a substrate material with a low loss tangent value improved energy harvesting efficiency. As a result, by optimizing the resistance values and substrate material properties of the SRR structure, energy harvesting efficiencies of up to 90% and electromagnetic absorption rates of up to 100% were achieved. These findings highlight the potential of SRR and similar metamaterial structures in energy harvesting and electromagnetic absorption applications.
