Overcoming Half-Space Blockage: Airy Beamforming for Radiative Near-Field Multiuser XL-MIMO Communications
Next-generation wireless systems with extremely large-scale antenna arrays (ELAAs) operate in the radiative near-field (RNF) region, where distance-aware focusing is feasible but is easily interrupted by half-space obstacles such as walls and corners. When the aperture-to-user path is clipped by a knife edge, conventio...
