Broadband Interferenceless Perfect Absorption in Hexagonal Boron Nitride and Lithium Fluoride Hyperbolic Metamaterial

open access: yesAdvanced Photonics Research, EarlyView.
The images (a) and (b) illustrate a composite metamaterial with anisotropic permittivity. When incident light, polarized in transverse magnetic or transverse electric modes, enters the structure, the reflectance spectra in (c) and (d) show low reflection and high absorption over a wide range of incidence angles. This behavior has potential applications
