What is VANTA black? The term VANTA is an acronym derived from the Vertically Aligned Nano-Tube Array or in short VANTA. Usually, the nanotubes in this design are made up of carbon. Since the colors we observe are usually the corresponding wavelengths of the solar spectrum in the visible domain

Metamaterial/ Metasurface absorbers In the previous post about classical perfect light absorbers, we discussed the thin film based absorbers in the shape of Salisbury screen absorbers and Jaumann absorbers. Now, these thin film based absorbers, especially the Salisbury screen, can be titled as an early demonstration of metasurface absorbers as

Absorbers An absorber is a device that partially or completely absorbs the incoming light or an EM wave for which it is designed. Absorption is one of the three phenomena that can happen to light as it hits the object. When light falls on an object, depending on the complex
