Suppression of the slot-mode propagation in a slitted waveguide
Bibliographic record
Abstract
Periodic transverse slots are introduced to a slitted waveguide for the purpose of suppressing slot-mode propagation. The effect of the transverse slots on the perturbed TE 10 mode are investigated using the finite-difference time domain (FDTD) method and periodic boundary conditions. Simulation results for two designs are presented and compared with analytical results. The first design suppresses the slot-mode propagation over a large portion of the X-band bandwidth. The second design uses minimal perturbation to suppress the slot-mode radiation while minimizing the impact on the propagation characteristics of the perturbed TE 10 mode. It will be shown that designs with wideband and narrowband suppression of the slot-mode are possible. However, it will be seen that the wider band the suppresion, the larger the perturbed TE 10 mode wavenumber deviates from the slitted results.

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.
