Abstract
An asymmetric frequency selective surface (FSS) based on Jerusalem cross-slot (JC-SL) unit cell is used as a polarization converting surface (PCS) to change the sense of the circularly polarized (CP) wave as it passes through it. This is achieved by introducing 0 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> and 180 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> phase shifts for the two perpendicular linear polarized components of the CP wave. Without adding any extra phase shift, the transmitted CP wave will encounter a change in its sense of polarization. The PCS is then combined with a bidirectional CP slot antenna to achieve right-hand CP (RHCP) signal on both sides of the antenna. The overall size of the structure is about 0.75λ×0.75λ×0.15λ, where λ is the free-space wavelength. The structure is designed to operate at the GPS L1 band ( f = 1.575 GHz).

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
