Abstract
A new concept is proposed for reducing the number of active antenna elements in a scannable phased array. The proposed approach is based on the recent concept of the Huygens’ metasurface. In such a metasurface, the fields in a given region are controlled by electromagnetic sources on the boundary surface of this region. Using this approach, a peripherally excited (PEX) metallic cavity is engineered to radiate a beam by appropriately perforating its top surface. This pencil beam can be scanned by simply changing the phases of the peripheral sources. The proposed concept has the potential to drastically reduce the required active elements in 2D phased arrays without compromising directivity. However, this also leads to constraints on the possible beam-pointing directions.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
