Metasurface provides a powerful platform to correct the chromatic aberration of conventional
lenses in a flexible, integratable, and ultra‐compact manner. Mid‐wavelength infrared has …

Existing mid-infrared thermographic cameras rely on a stack of refractive lenses, resulting in
bulky and heavy imaging systems that restrict their broader utility. Here, we demonstrate a …

The metalens has vast applications in biomedicine and industrial manufacturing due to their
ultrathin structure and vital ability to manipulate the properties of light waves for long-infrared …

Enhancing light-matter interaction by exciting Dirac plasmons on nanopatterned monolayer
graphene is an efficient route to achieve high infrared absorption. Here, we designed and …

Infrared lenses have a wide range of applications in thermal imaging and detection. Here, by
designing a single layer metasurface consisting of anisotropic microstructures, we …

In this paper, we introduce three different metasurfaces that can achieve subwavelength
focusing of the radiation in the infrared domain. The structures presented achieve high …

Frequency selective detection of low energy photons is a scientific challenge using natural
materials. A hypothetical surface which functions like a light funnel with very low thermal …

We demonstrate a flat optical lens based on plasmonic reflectarray metasurface, which
consists of a planar array of hyperbolic-shaped aluminum (Al) nanoantenna separated from …

Surface lattice plasmon resonances (SLPR) in periodic arrays of metal nanostructures can
feature a narrow spectral linewidth in case of the spectral overlap between the localized …

Gradient refractive index (GRIN) metamaterial lenses can achieve multi-band fusion infrared
imaging and has the characteristics of integration, light weight, and achromaticity, compared …
