MULTI-POLARIZATION DIMENSIONALITY OF MULTI-ANTENNA SYSTEMS
Bibliographic record
Abstract
Abstract—Based on the deterministic Maxwellian framework, we investigate the ability of each of the dual fields (electric and magnetic) in carrying independent information in a multi-polarization MIMO system. We quantify the performance by using a well-defined power independent dimensionality (PID) metric. We present numerical results for 3 deterministic scenarios: a canonical free-space (near and far field exact solution), a canonical PEC corridor (using rigorous modal analysis) and a lossy-wall corridor (using image ray tracing). The deterministic results show that in a multi-path rich environment, the hexapole system (collocated polarized electric and magnetic point radiators) is almost guaranteed to provide more than 3 DOF. However, in the simulated scenarios, the maximum 6 DOF are never attained due to the inevitable coupling between the electric and magnetic fields. On the other hand, for a tripole system, the upper-limit of 3 DOF is achievable. 1.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
