Spectrum of corrugated circular waveguides from generalized scattering matrix of unit cell using EM Solvers
Bibliographic record
Abstract
In this paper the spectrum of corrugated circular waveguides will be computed from classical matrix eigenvalues. Both cases of single and dual-depth corrugations are shown. The eigenvalue problem is formulated by means of generalized scattering matrix extracted from HFSS or any other 3D field solver where the eigenvalues are directly related to the propagation constants. New techniques to force the EM solver to excite selected modes will be presented. In addition to the advantage of only investigating the modes of interest, these techniques reduce computation time significantly by shrinking the computational domain. Corrugated circular waveguides are simulated using these techniques and results are compared to those computed from CIET. Excellent agreement is achieved. Also the spectrum of dual-depth corrugated circular waveguide is computed using the same techniques.

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.
