This article reveals and numerically analyzes a three-layer ultrawide-band nanostructured game of thrones jon snow poster metamaterial absorber (MMA) formed of nickel, silicon dioxide, and nickel.It is possible to attain an absorption rate greater than 99 % for a bandwidth of 325 nm in the optical spectrum and an absorption rate of 95.91 % with a bandwidth of 2785 nm, spanning from 215 nm to 3000 nm (ultraviolet (UV) to near infrared (NIR) wavelength regions).

The stability of absorption properties is observed for a large range of oblique incidence angles and polarization angles.Mechanical bending, which may arise due to extraneous stresses, has been found to have almost the same rate 2023 little mermaid cake of absorption.The numerical analysis is verified theoretically using the interference theory (IT) model, and the ideal MMA characteristics are confirmed by the polarization conversion Ratio (PCR).

The demonstrated MMA exhibits potential applications across diverse domains such as solar energy conversion, biomedical engineering, and sensing technology.
