Abstract
We propose a new topology for printed circuit board metagratings (MGs) for manipulation of electromagnetic waves at microwave frequencies. By interleaving two single-band segmented gratings (SGs), a composite device capable of performing dual-band operation is realized. The constituent SGs are designed independently, meaning the two operating frequencies need not be harmonically related. The SGs are shielded from one another through inclusion of via fences which suppress near-field coupling. They are each engineered to be inactive within the other's operating band, which helps retain their individually encoded functionalities. Using the proposed topology, a dual-band MG that performs perfect anomalous reflection of plane waves at 10 and 15.11 GHz is designed. The device is verified both numerically and experimentally.

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
