The work introduces a two-stage non-uniform polar codebook and a fast-scanning 1D codebook for Airy beam training that cut overhead by 54% and 93% respectively versus prior hierarchical methods while preserving spectral efficiency.
An analytical framework characterizes Airy beam propagation in near-field XL-MIMO, derives aperture and spacing constraints for distortion-free trajectories, and quantifies trade-offs versus Gaussian beams.
Derives closed-form Airy beam trajectory dispersion across THz subcarriers via Fresnel integral and introduces TTD-assisted beamforming to control it for sensing or communication.
A review of bending beam fundamentals, applications, and challenges for THz wireless communications, with a 140 GHz metasurface prototype demonstrating 1.6 Gbps through a blocked link.
