Holographic Imaging with XL-MIMO and RIS: Illumination and Reflection Design
This paper addresses a near-field imaging problem utilizing extremely large-scale multiple-input multiple-output (XL-MIMO) antennas and reconfigurable intelligent surfaces (RISs) already in place for wireless communications.
Near and Far Field Model Mismatch: Implications on 6G Communications, Localization, and Sensing
The upcoming 6G technology is expected to operate in near-field (NF) radiating conditions thanks to high-frequency and electrically large antenna arrays.
Radio SLAM for 6G Systems at THz Frequencies: Design and Experimental Validation
Next-generation wireless networks will see the convergence of communication and sensing, also exploiting the availability of large bandwidths in the Terahertz (THz) spectrum and electrically large antenna arrays on handheld devices.
Near-field Localization with Dynamic Metasurface Antennas
We use a direct positioning estimation method based on curvature-of-arrival of the impinging wavefront to obtain the user location, and characterize the effects of DMA tuning on the estimation accuracy.
6G Wireless Communications: From Far-field Beam Steering to Near-field Beam Focusing
As a consequence, it is expected that some portion of future 6G wireless communications may take place in the radiating near-field (Fresnel) region, in addition to the far-field operation as in current wireless technologies.
Near-Field Wireless Power Transfer with Dynamic Metasurface Antennas
Radio frequency wireless power transfer (WPT) enables charging low-power mobile devices without relying on wired infrastructure.
Near-field Wireless Power Transfer for 6G Internet-of-Everything Mobile Networks: Opportunities and Challenges
Radiating wireless power transfer (WPT) brings forth the possibility to cost-efficiently charge wireless devices without requiring a wiring infrastructure.
Beam Focusing for Near-Field Multi-User MIMO Communications
As the ability to achieve beam focusing is dictated by the transmit antenna, we study near-field signaling considering different antenna structures, including fully-digital architectures, hybrid phase shifter-based precoders, and the emerging dynamic metasurface antenna (DMA) architecture for massive MIMO arrays.
Near-field Tracking with Large Antenna Arrays: Fundamental Limits and Practical Algorithms
In this paper, we study a near-field tracking problem for inferring the state (i. e., the position and velocity) of a moving source with an ad-hoc observation model that accounts for the phase profile of a large receiving array.

Reinforcement Learning for UAV Autonomous Navigation, Mapping and Target Detection
In this paper, we study a joint detection, mapping and navigation problem for a single unmanned aerial vehicle (UAV) equipped with a low complexity radar and flying in an unknown environment.
Radio Positioning with EM Processing of the Spherical Wavefront
Next 5G and beyond applications have brought a tremendous interest towards array systems employing an extremely large number of antennas, so that the technology that might be in place for communication can be also exploited for positioning.
