Despite significant advances, scalable production of artificial photonic radiators with periodic structures, environmental stability, high radiative cooling performance, and economic applicability is still challenging in most state-of-the-art radiative coolers. Rational structure and materials design are essential to promote daytime sunlight reflectance while maintaining a high emissivity within the atmospheric window (8-13 µm). In this work, inspired from the unique hair structure of heat-resistant organisms, a biomimetic micro-pyramid shaped structure model is analyzed.
