Near-Field Spot Beamfocusing: A Correlation-Aware Transfer Learning Approach
Three-dimensional (3D) spot beamfocusing (SBF), in contrast to conventional angular-domain beamforming, concentrates radiating power within a very small volume in both radial […]
A Study on Characterization of Near-Field Sub-Regions For Phased-Array Antennas
We characterize three near-field sub-regions for phased array antennas by elaborating on the boundaries Fraunhofer , radial-focal , and non-radiating distances. The […]
6G Fresnel Spot Beamfocusing using Large-Scale Metasurfaces: A Distributed DRL-Based Approach
We propose a novel approach to smart spot-beamforming (SBF) in the Fresnel zone leveraging extremely large-scale programmable metasurfaces (ELPMs). A smart SBF […]
