Abstract
This paper presents the design, fabrication, and measurement of three phase-correcting lens antennas made using an electrically thin three-layer phase-shifting surface (PSS). The three phase-correction schemes realised using the PSS are the 90 degree, 45 degree and quasi-continuous cases. These lenses, which present identical cost, size and weight, are compared in terms of their far-field performance. It is shown that decreasing the size of the phase steps used in the phase-correction scheme improves the performance of the PSS lenses. As a reference to conventional designs, the performance of a dielectric plano-hyperbolic lens antenna is also presented. The performance of the PSS lenses are as good as, or better, than this conventional dielectric lens antenna within a specific operating band, over which they also offer a significant reduction in weight, thickness and cost.

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
