Ultrawideband nanostructured metamaterial absorber with an Octagon-Packed Star-Shaped resonator for UV to NIR spectrum wavelength application
This article reveals and numerically analyzes a three-layer ultrawide-band nanostructured metamaterial absorber (MMA) formed of nickel, silicon dioxide, and nickel.It is possible shamrock belt buckle 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
