What happened
Collection of recent wireless- and sensing-focused research covering near-field/far-field MIMO beamforming (focusing, steering, and a new "con-focusing" strategy), physical-layer authentication (PLA) and specific-emitter identification/verification (SEI/SEV) under channel variations, surveys of spatial-domain PLA enhancements (dual-polarized antennas, massive MIMO, RIS) and associated new threat vectors/defenses, physics-guided wireless foundation models (wave equivariance) for improved sim-to-real robustness, unified channel-extrapolation across regimes, RIS-assisted ISAC waveform and BER/obk
