Holographic Imaging with XL-MIMO and RIS: Illumination and Reflection Design
Giulia Torcolacci, Anna Guerra, Haiyang Zhang +4
This paper addresses a near-field imaging problem utilizing extremely large-scale multiple-input multiple-output (XL-MIMO) antennas and reconfigurable intelligent surfaces (RISs) a…
NLOS Localization Exploiting Frequency-selective Metasurfaces
Marina Lotti, Giacomo Calesini, Davide Dardari
This paper introduces a new approach to localize user devices located in non-line-of-sight (NLOS) areas using a passive, non-reconfigurable, and frequency-selective metasurface cal…
Holographic MIMO Communications exploiting the Orbital Angular Momentum
Giulia Torcolacci, Nicolò Decarli, Davide Dardari
This study delves into the potential of harnessing the orbital angular momentum (OAM) property of electromagnetic waves in near-field and line-of-sight scenarios by utilizing large…
Reconfigurable Electromagnetic Environments: A General Framework
Davide Dardari
The recent introduction of the smart radio environments (SREs) paradigm, enabled by reconfigurable intelligent surfaces (RISs), has put in evidence the need for physically-consiste…
Spatial Multiplexing in Near Field MIMO Channels with Reconfigurable Intelligent Surfaces
Giulio Bartoli, Andrea Abrardo, Nicolo Decarli +2
We consider a multiple-input multiple-output (MIMO) channel in the presence of a reconfigurable intelligent surface (RIS). Specifically, our focus is on analyzing the spatial multi…
