In this contribution, we describe a simple and effective approach for the design of phase-gradient metasurfaces based on Huygens cells for oblique incidence. The approach is based on conventional microwave networks and accounts for off-normal incidence onto the cells and for their different response for the two orthogonal polarizations. In addition, it is reported a simple example in which the performance of the angularly-optimized phase-gradient metasurface is compared to the one of an equivalent device designed under normal incidence condition.

Abstract
In this contribution, we describe a simple and effective approach for the design of phase-gradient metasurfaces based on Huygens cells for oblique incidence. The approach is based on conventional microwave networks and accounts for off-normal incidence onto the cells and for their different response for the two orthogonal polarizations. In addition, it is reported a simple example in which the performance of the angularly-optimized phase-gradient metasurface is compared to the one of an equivalent device designed under normal incidence condition.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
