Abstract
The paper presents a dual circular polarization unit cell for realizing a reflectarray that synthesizes two independent patterns based on the polarization of the incident field. To this end, a thin polarizer, which converts incident circularly polarized (CP) waves into orthogonal linearly polarized (LP) waves, is cascaded with a dual-linear-polarization (DLP) reflectarray. The reflectarray then applies the required reflection phases to the LP waves. The proposed antenna system is structured by placing the polarizer adjacent to the DLP reflectarray. Numerical simulations are arranged to assess the performance and ability of a 20 GHz unit cell design in providing high polarization purity and independent reflection phases for orthogonal CP waves. Enclosing 4×4 polarizer cells as small as 0.14λ×0.14λ, the unit cell features an overall thickness of ~1λ and lateral dimensions of 0.55λ×0.55λ.

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
