Ultra-broadband nanowire metamaterial absorber
文献摘要：
Broadband absorbers generally consist of plasmonic cavities coupled to metallic resonators separated by a dielec-tric film,and they are vertically stacking configurations.In this work,we propose an ultra-broadband nanowire metamaterial absorber composed of an array of vertically aligned dielectric nanowires with coaxial metallic rings.The absorber shows strong absorption from 0.2 to 7 μm with an average absorption larger than 91％due to the excitation of gap surface plasmon polariton modes in Fabry-Perot-like resonators.Moreover,a refractory dielec-tric cladding can be added to improve the thermal stability of the absorber,showing a negligible impact on its absorption performance.The proposed absorber may find potential applications in solar energy harvesting,infra-red imaging and spectroscopy,and optoelectronic devices.
