Light absorption is a cornerstone for several applications such as solar cells, photodetectors, and optical sensors, to name a few. Yet, the trade-off between the thickness of the absorber and its ...

Perfect absorption arises from the strong interaction of valence electrons with light in a conducting material. Optical metamaterial is an effective approach to exploit the superior photon capture ...

We designed an ultra-broadband graphene absorber structure with the applied resonator design based on the Al-AlSb-Cr structure, and a thin effective layer of graphene is inserted. To develop the role ...

Researchers from the Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences have recently proposed a design concept for a tunable broadband perfect absorber based on ...

With the advancement in science and technology and rapid decrease in the cost of electrical, electronic equipment, energy demand is increased rapidly over the period. It is very difficult and not ...

Broadband metamaterial-based perfect absorbers (MPAs) have significant potential in many applications. However, the design and fabrication of ultra-broadband terahertz MPAs pose considerable ...
