Infrared all-dielectric kerker metasurfaces
Webb29 mars 2024 · We further describe the perfect absorption mechanism in all-dielectric metasurfaces through development of an extended Kerker formalism. The … WebbMetasurfaces, metamaterials, and nanoantennas are the main building blocks of nanophotonics allowing giant field enhancement and precise control over light at the subwavelength scale. Their optical properties are strongly governed by the response of meta-atoms – their elementary units.

WebbOptically thin perfect light absorbers could find many uses in science and technology. However, most physical realizations of perfect absorption for the optical range rely on … Webb1 jan. 2024 · One recent example lies in novel Huygens’ metasurfaces and metadevices that rely on the suppression of backward scattering due to the interference of electric and magnetic dipole modes (that is, due to the first Kerker condition). Such dielectric metasurfaces, in marked contrast to plasmonic metasurfaces, offer very high …

The unidirectional scattering of electromagnetic waves in the backward and forward direction, termed Kerkers’ first and second conditions, respectively, is a prominent feature of sub-wavelength particles, which also has been found recently in all-dielectric metasurfaces. Here we formulate the exact polarizability requirements necessary to achieve both Kerker conditions simultaneously with ... WebbPlasmonic applications are based on the optical processes that occur in nanostructures incorporating materials with negative permittivity and free-career oscillations. These processes involve coupling of light and the collective oscillation of electrons (known as plasmons) at the metal–dielectric interface.
