The AC resistance of a microstripline and its ground plane
Bibliographic record
Abstract
It is found that the RF resistance of a microstripline is substantially higher than the theoretical value from the skin effect of the strip alone. Based on rigorous analysis, it is determined that the extra resistance is caused mainly by the concentration of grounded plane current under a wide microstrip, and the concentration of the strip current toward the ground. It is pointed out that rigorous analytical results can be obtained for the total AC resistance R/sub t/ of a microstripline, since R/sub t/ is the sum of R/sub g/ of the ground plane and R/sub s/ of the strip. The rigorous results indicate that, for wide strips, R/sub g/ approaches R/sub s/, and R/sub s/ can be twice as great as R/sub AC/, the AC resistance of the same strip isolated (i.e. without ground plane). This means that the AC resistance of the microstrip R/sub t/ can be four times as large as the AC resistance R/sub AC/ of the same strip isolated. In turn, R/sub AC/ is larger than R/sub DC/.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
