In this contribution, we discuss the design of spatial filters realized through all-dielectric metasurfaces. Specifically, it is first discussed how the tangential polarizations of all-dielectric metasurfaces can be exploited to design wideband dielectric mirrors. Then, it is shown how it is possible engineering the normal polarization of these structures and use them to open a transmission window around a desired impinging angle. Several examples and realistic full-wave simulations are included to verify the analytical models and the physical discussions.

Abstract
In this contribution, we discuss the design of spatial filters realized through all-dielectric metasurfaces. Specifically, it is first discussed how the tangential polarizations of all-dielectric metasurfaces can be exploited to design wideband dielectric mirrors. Then, it is shown how it is possible engineering the normal polarization of these structures and use them to open a transmission window around a desired impinging angle. Several examples and realistic full-wave simulations are included to verify the analytical models and the physical discussions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
