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

Abstract

Perfect Absorption

Interferenceless perfect absorption holds significant potential for applications in photodetection, photovoltaics, and medical diagnostics. In article number 2400187, Yibin Tian, Rujiang Li, and co-workers present an innovative composite metamaterial made of hexagonal boron nitride and lithium fluoride layers. The proposed design achieves broadband interferenceless perfect absorption, independent of the polarization of the incident light field, and across a wide range of incident angles.
