Summary:Research about electromagnetic absorbers has accelerated, spurred by the potential applications of metamaterials within the optical region of the frequency spectrum. Polytetrafluoroethylene (PTFE), with its low refractive index, and resistance to oxidation, stands out among most absorption media. Its advantages include oxidation resistance, prolonged device lifespan, stability in the long term, and effectiveness within the visible electromagnetic spectrum [1]. Recent studies explore the use of PTFE in constructing metamaterial absorbers (MAs) via 3D printing technology. This approach capitalizes on 3D printing's evolution and versatility, enabling the production of MAs with enhanced flexibility, speed of production, and cost-effectiveness [2].
