In this contribution, we present the results of some preliminary investigations about the use of microplasma arrays as reconfigurable refractive metasurfaces at microwave frequencies. Through theoretical considerations and full-wave results, we demonstrate how reconfigurable Drude-like scatterers can serve as fundamental elements of multipolar metasurfaces, enabling full phase coverage in transmission. Additionally, we discuss the design of a reconfigurable planar lens capable of steering the beam emitted by an aperture antenna across a wide angular range.

Abstract
In this contribution, we present the results of some preliminary investigations about the use of microplasma arrays as reconfigurable refractive metasurfaces at microwave frequencies. Through theoretical considerations and full-wave results, we demonstrate how reconfigurable Drude-like scatterers can serve as fundamental elements of multipolar metasurfaces, enabling full phase coverage in transmission. Additionally, we discuss the design of a reconfigurable planar lens capable of steering the beam emitted by an aperture antenna across a wide angular range.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
