Extremely Backscattering Suppression Structure In their Research Article (DOI: 10.1002/adma.202512727), Benfeng Bai, Xiaopeng Hao, Hong-Bo Sun, and co-workers report a hierarchical structure with nanodefects that exhibits extremely backscattering suppression of broadband infrared light. They discovered and utilized an energy negative feedback regulation mechanism in laser-material interaction to achieve this. This structure can achieve a suppression of over 98%, which can be used for making high-performance blackbodies, offering a promising route toward precise infrared calibration and detection.
