What happened
Batch of arXiv submissions (May 21, 2026) spanning antenna/EM engineering, wireless systems, information theory, ML, and quantum sensing. Key technical contributions: (1) Stacked Intelligent Metasurfaces (SIMs) for extending engineering-usable near-field distance (UNFD) and improving axial/lateral focusing for 6G/ISAC; (2) holographic MIMO “super‑beamforming” showing mutual‑coupling-enabled quadratic gain scaling in certain geometries; (3) rotatable and flexible coupler antenna (RCA/FCA) concepts for mechanical beamforming using passive couplers to lower RF‑chain count; (4) forward ANS and an–
