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 to attain an absorption rate greater than 99 % for a bandwidth of 325 nm in the optical spectrum and an absorption rate of 95. https://www.chiggate.com/loving-earth-jilungin-dreaming-tea-30g-cheap/
