What happened
Collection of new arXiv submissions (Mar 9, 2026) focused on advanced wireless signal processing, coding, and covert/semantic communications. Key security-relevant contributions: XL-RIS and CAPA analyses of physical-layer secrecy (beamforming, artificial jamming, secrecy-rate/SOP expressions, near-field/eavesdropper effects); STAR/BD-RIS modeling with per-element amplification and emission caps (hardware-accurate signal model and constrained optimization); distributed semantic-alignment and interference-management for goal-oriented communications; Alkaid — a provably secure steganographic enc/
