Abstract
Radar absorbing surfaces with excellent 100% bandwidth have been made possible lately with square loops of resistive strip. However, a setup with such absorbing surface may still need an extra antenna to maintain outside communication and this could be cumbersome. If such broadband absorbing surface is made of an array of actual antennas, and one or a few of them can be tapped for outside communication when needed, then the extra antenna is not needed. This paper shows that indeed an array of folded-dipoles, forming square loops, can be designed for such purpose and bandwidth through optimization. The optimization is actually quite simple, by manual manipulations of the impedance locus in Smith chart.

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
