Abstract
The recent implementation of negative-refractive-index (NRI) media by periodically loading host transmission-lines (TL) with lumped-element series capacitors and shunt inductors has led to the development of numerous practical devices based on NRI-TL metamaterials (MTM). The MTM feed networks were shown to be useful in series-fed linear arrays for effectively replacing one-wavelength long conventional meandered transmission lines, thus achieving compact, broadside radiators, whose beam squints less with frequency. In addition, the MTM feed networks can be used to create linear arrays whose main beam remains virtually fixed at a negative angle from broadside as the frequency is varied. Alternatively, a single CPS MTM feedline operating inside the radiation cone can be used to implement a leaky-wave antenna (LWA), which can be recognized as the dual of the CPW line to create a backward LWA

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
