One of the main challenges in research beyond 5G and 6G networks is the fruition of smart propagation environments. Reconfigurable Intelligent Surfaces (RIS) represent a promising technology for realizing controllable wireless propagation environments that can actively cooperate in data transfer and processing. A reconfigurable PIN-loaded metamaterial unit-cell is investigated for next-generation communications, Device-to-Device systems and Internet of Things. The proposed cell allows to implement switchable reflector/absorber surfaces for different polarizations, to selectively allow/inhibit signal transmission with respect to the polarization of the impinging wave.

Abstract
One of the main challenges in research beyond 5G and 6G networks is the fruition of smart propagation environments. Reconfigurable Intelligent Surfaces (RIS) represent a promising technology for realizing controllable wireless propagation environments that can actively cooperate in data transfer and processing. A reconfigurable PIN-loaded metamaterial unit-cell is investigated for next-generation communications, Device-to-Device systems and Internet of Things. The proposed cell allows to implement switchable reflector/absorber surfaces for different polarizations, to selectively allow/inhibit signal transmission with respect to the polarization of the impinging wave. Thanks to its features, the proposed metamaterial configuration could be very attractive for designing and customizing RIS prototypes for specific communication scenarios.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
