The article presents a novel design for an ultrathin (260 nm) plasmonic super absorber that achieves broadband and polarization-independent resonant light absorption over the entire visible spectrum (400–700 nm). The super absorber consists of a metal-insulator-metal (MIM) stack with a nanostructured top silver film composed of crossed trapezoidal arrays. This design allows for high absorption with an average measured absorption of 0.71 and simulated absorption of 0.85. The authors demonstrate that the absorption is independent of the incident polarization due to the symmetric arrangement of the crossed trapezoid array geometry. The study also explores the impact of different polarization angles and incidence angles on the resonant absorption, showing that broadband resonant absorption is maintained even at high angles of incidence. The design has potential applications in thin-film thermal emitters, photovoltaic cells, and solar cells, offering a promising approach to achieving 'black' materials with large broadband absorption.The article presents a novel design for an ultrathin (260 nm) plasmonic super absorber that achieves broadband and polarization-independent resonant light absorption over the entire visible spectrum (400–700 nm).
