In this work, we introduce a cross-shaped based-metamaterial absorber (CSMA) which enables an ultra-broadband over the visible to near-infrared regions with high absorption of over 95%. This CSMA structure possesses high solar to thermal efficiency, broadband absorption spectra. Furthermore, we ...
The mechanisms of the ultra-broad absorption band of the absorber are that multiple localized surface plasmon resonances are excited in the metasurface and the hybridization of the graphene and gold patterns enhances the field in the metasurface. Besides, the multiple reflections of incidence between ...
The absorber, which covers near infrared (NIR) and visible (Vis) ranges, consists of a metal-insulator-metal-insulator (MIMI) multilayer where the middle metal layer has a variant thickness. It is found that this non-uniform thickness of the metal provides us with an absorption that is much...

This remarkable efficient, ultra-broadband and wide angular performance is demonstrated by carefully designed experiments in the near infrared regime, showing good agreement with numerical results.Similar content being viewed by others Ultra-high-Q resonances in plasmonic metasurfaces Article Open access ...
The coupled modes extend the perfect absorption band to the near-infrared region (150 nm–4200 nm). This design has potential application in photovoltaic devices and thermal emitters. Introduction In energy harvesting field, it has attracted great interest to realize broadband and angle-insensitive ...
Employing accurately designed metasurfaces is another class of designs to achieve this property26,27,28. However, two important issues are raised taking the aforementioned ideas into consideration; 1) most of these works are implemented for infrared (IR), terahertz (THz), and gigahertz (GHz) ...
