Abstract
The authors investigate the possibility of changing the phase of central elements of a phased-array antenna to granulate the main beam positions at each course step. The effect of such changes in the phases of both central and edge elements on the radiation pattern characteristics is also investigated. A phased-array antenna with an average beam step size requirement of 0.02 degrees is considered for the purposes of illustration. It is shown that for a given delta , the main beam position depends on the number of elements and the aperture distribution. Furthermore, there is more than one combination, that is, number of elements an inherent phase shift, to yield almost the same position for the main beam. Thus, to determine which combination should be used to produce a particular beam position, the effect of each combination on the radiation pattern characteristics, that is, the sidelobe levels, is studied.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
