In this contribution, we discuss two different strategies aimed at tailoring the electric and magnetic response of an all-dielectric metasurface. Specifically, we investigate the possibilities enabled by two different families of core-shell meta-atoms: concentric all-dielectric spheres and homogenous spheres covered by a reactive layer. The analysis of the scattering properties of these two classes of particles reveals intriguing effects that can be used for the design of innovative metasurfaces exploiting the entire multipolar response of their meta-atoms. Several examples are considered and investigated both analytically and numerically.

Abstract

In this contribution, we discuss two different strategies aimed at tailoring the electric and magnetic response of an all-dielectric metasurface. Specifically, we investigate the possibilities enabled by two different families of core-shell meta-atoms: concentric all-dielectric spheres and homogenous spheres covered by a reactive layer. The analysis of the scattering properties of these two classes of particles reveals intriguing effects that can be used for the design of innovative metasurfaces exploiting the entire multipolar response of their meta-atoms. Several examples are considered and investigated both analytically and numerically.
