Abstract
Antennas for microwave heating radiate high levels of power relative to communications and most radar applications. The problem of voltage breakdown becomes a dominant factor in the antenna design. The breakdown problem is compounded when the heating is in a partial vacuum, which can be worse than the full vacuum situation of space-borne antennas. Resonant slot array antennas are ideal for microwave heating because of their variable aperture design and high efficiency except for the slot voltage breakdown problem. This paper presents new design results for antenna array design for microwave heating, based on maximum electric-field considerations. As an example design, a seven-slot waveguide array with a slot width of λ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> /4 is found to be suitable for 1 kilowatt (a typical magnetron), based on a criteria of keeping the electric field below 3% of free-space breakdown.

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
