The resonant nanostructures are significant for enhancing the electromagnetic field density
in a nanoscale region, suitable for many novel nanophotonic applications. This review …

In this paper, a kind of dynamically tunable graphene metasurface which can act as a multi-
band refractive index sensor or a four-state optical switch is proposed. Based on the …

This paper proposes a novel model for an high-efficiency tunable broadband near-infrared
absorber. The proposed absorber consists of an Al bottom mirror, SiO 2-VO 2 hybrid spacing …

Huygens metasurfaces have demonstrated remarkable potential in perfect transmission and
precise wavefront modulation through the synergistic integration of electric resonance and …

With current trends to progressively miniaturize optical systems, it is now essential to look for
alternative methods to control light at extremely small dimensions. Metalenses are …

Optical edge-enhanced imaging is an effective method for boundary extraction, and it is also
a cutting-edge technology for object detection in image processing. With the rapid …

Once the metalenses are fabricated, the functions of most metalenses are invariable. The
tunability and reconfigurability are useful and cost-saving for metalenses in realistic …

In intense-light systems, the traditional discrete optical components lead to high complexity
and high cost. Metasurfaces, which have received increasing attention due to the ability to …
