Broadband Perfect Absorber Based on TiN-Nanocone Metasurface
Based on an integrated array of refractory titanium nitride (TiN), a metasurface perfect absorber (MPA) in the visible-to-near infrared (NIR) band is reported.The systematic and detailed simulation study of the absorption of the MPA is performed with the finite-different time-domain (FDTD) method.Tailoring the structure, the MPA realizes as high an
