An Infrared Ultra-Broadband Absorber Based on MIM Structure

An Infrared Ultra-Broadband Absorber Based on MIM Structure

We designed an infrared ultra-broadband metal–insulator–metal (MIM)-based absorber which is composed of a top layer with four different chromium (Cr) nano-rings, an intermediate media of aluminum trioxide (Al<sub>2</sub>O<sub>3</sub>), and a bottom layer of tungsten (W). By u...
