Wavefront Engineering for Physical Layer Security in Near-Field Wireless Communications
Sotiris Droulias, Angeliki Alexiou
With wireless transmission exposing information to potential interception by unintended receivers, physical layer security (PLS) offers a promising approach to securing wireless co…
Radial-Angular Resolution Framework for Near-Field Communications
Viviana Centritto, Sotiris Droulias, Angeliki Alexiou
Near-field beamfocusing confines radiated power into a localized three-dimensional focal spot, making the analytical characterization of radial and angular resolution critical for…
Analytical Framework of Radial Resolution for Near-Field Communications
Viviana Centritto, Sotiris Droulias, Angeliki Alexiou
As extremely large antenna arrays (ELAAs) become central to next-generation wireless systems, the transition into the near-field propagation regime enables the exploitation of sphe…
Unified Evaluation Methodology for AI-Native Integrated Sensing and Communication
Filip Lemic, Andra Blaga, Francesco Devoti +24
Integrated Sensing and Communication (ISAC) couples radio sensing, data transmission, and control actions within a single closed-loop system. When Artificial Intelligence (AI)-driv…
Bending beams behind corners: mechanisms, challenges and capabilities for wireless connectivity
Sotiris Droulias, Angeliki Alexiou
Curved beams, that is, beams that are able to propagate on nonlinear trajectories, are often envisioned as ideal candidates for blockage avoidance in future wireless connectivity.…
Enhancing the physical layer security with bending beams
Sotiris Droulias, Giorgos Stratidakis, Angeliki Alexiou
Wavefront engineering for applications in near-field wireless connectivity is gradually becoming common ground. In this landscape, beams that propagate on bent paths are ideal cand…
