Guided-wave characteristics of periodically nonuniform coupled microstrip lines-even and odd modes
Bibliographic record
Abstract
Even- and odd-mode guided-wave characteristics of periodically nonuniform coupled microstrip lines (PNCML) are thoroughly investigated in terms of the two sets of per-unit-length transmission parameters, i.e., characteristic impedance and phase constant. By executing the short-open calibration (SOC) procedure in the method-of-moments platform, the two-port ABCD matrices of the PNCML with finite unit cells are numerically deembedded via two sets of SOC standards so as to explicitly derive the effective per-unit-length parameters. After our investigation on the behaviors of numerical convergence, extensive results are derived to demonstrate the frequency- and periodicity-dependent per-unit-length parameters of the three types of PNCML against those of the uniform coupled microstrip line. In final, the S-parameters of a PNCML circuit are directly simulated via extracted per-unit-length parameters and they are validated in magnitude and phase by those from the Momentum simulator.

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.
