Holographic Airy beamforming on reconfigurable surfaces generates curved trajectories in THz to bypass blockages, yielding over 10 dB received power gain versus traditional arrays in simulations.
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.
Derives closed-form throughput expressions for beamfocusing (with optimal dwell time accounting for defocusing) and caustic beamforming (invariant to user speed), plus an analytically established overhead threshold that vanishes at high frequencies favoring CB.
