Metasurfaces are revolutionizing the way we can control and manipulate light. Unprecedented functionalities, such as anomalous reflection and refraction, can be achieved using ultrathin surfaces textured at nanoscale. The aim of this contribution is reviewing our recent efforts in the development of analytical models able describing the response of some widely-used classes of optical metasurfaces. We show, both theoretically and through full-wave simulations, that arrays of spheroidal nanoparticles can be fully characterized relying on the surface impedance concept, and that the availability of such models enables the design of innovative optical devices and components.

Abstract
Metasurfaces are revolutionizing the way we can control and manipulate light. Unprecedented functionalities, such as anomalous reflection and refraction, can be achieved using ultrathin surfaces textured at nanoscale. The aim of this contribution is reviewing our recent efforts in the development of analytical models able describing the response of some widely-used classes of optical metasurfaces. We show, both theoretically and through full-wave simulations, that arrays of spheroidal nanoparticles can be fully characterized relying on the surface impedance concept, and that the availability of such models enables the design of innovative optical devices and components.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
