Near-infrared six-band polarization-independent wide-angle absorber based on metal cavity arrays filled with GaAs

摘要

＜正＞Dear editor,Since the first microwave metamaterial perfect absorber （MPA） was reported by Landy et al.[1],the study of metamaterial perfect absorbers has attracted attention because of their broad application prospects. Owing to the strong resonant nature of metamaterials, MPAs generally
