Titanium nitride (TiN) metadevices as perfect absorbers are studied using finite-difference time-domain (FDTD) simulations. In this paper, we demonstrate a metastructure including a top silica (SiO 2 ) layer, two layers of TiN nano-ribbon arrays, a SiO 2 dielectric layer, and a TiN film to realize e...
