Infrared all-dielectric kerker metasurfaces

Webb29 apr. 2024 · The designed all-dielectric metasurface superabsorber shows high- Q (∼640) near-unity absorption in the near-infrared region. Moreover, when the superstrate refractive index is different from that of the substrate, the anticrossing behavior of the induced dipole quasi-BIC resonances can be observed in the absorption spectra.

WebbRecently, all-dielectric metasurfaces composed of multiple microscale scatterers, which split and focus light in four or six different polarization bases, were reported with high transmission to realize full-Stokes detection of incident light [11,29 –31]. WebbWe believe that high efficient all-dielectric metasurfaces with the unprecedented capability of the polarization control can be widely applied in areas of polarization detection and imaging, data encryption, display, optical communication and quantum optics to realize ultracompact and miniaturized optical systems. bungalows for sale in kimberley notts https://penspaperink.com
