Abstract
ABSTRACT Electrical properties and geometrical characteristics of frequency‐selective‐surface‐loaded quasi‐transverse electromagnetic (TEM) rectangular waveguides are investigated in detail. The properties of electrical field distributions over the cross section of waveguides at various periodical phase shift points are studied. The phenomena, in connection with artificial magnetic conductor (AMC), cavity resonance, and surface resonance, are discussed. A definition of bandwidth for AMC is proposed on the basis of the variation of average z ‐polarized electric fields along z ‐axis between two side dielectric surfaces. Standard deviation technique is used to describe the uniformity of electrical fields and cavity efficiency is defined to represent the percentage of useful cavity with uniform electrical fields. The dispersion relationship, bandwidths of AMC and single mode, and cavity efficiency for various types of AMC surfaces are examined and compared. The geometrical characteristics of quasi‐TEM waveguides are studied in both theory and experiment. Design rules for high‐quality quasi‐TEM waveguides are proposed.

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
