Broadband polarization-asymmetric directional thermal emission enabled by opposite phase-gradient metasurfaces

Abstract Thermal emission from natural materials is typically broadband and weakly structured in angle and polarization, limiting its utility for customized infrared functionalities. Here we demonstrate a metasurface platform that realizes broadband polarization-asymmetric directional thermal emissi...
