Single-Layer Substrate-Integrated Waveguide Inline Filters With Flexible Transmission Zeros
Bibliographic record
Abstract
This letter presents a novel class of single-layer substrate-integrated waveguide (SIW) inline filters with flexible transmission zeros (TZs). The basic structure is an oversized half-mode SIW (HMSIW) rectangular cavity (RC) perturbed by a pair of metallic via-holes or an open-ended slotline. Each perturbed HMSIW RC can provide one pole and two TZs. By changing the distance between the perturbation via-holes or the length of the perturbation slotline, one TZ can be moved either above or below the passband, while the other is always located above the passband. Based on these perturbed HMSIW RCs, two SIW three-pole inline filters are fabricated and measured to validate the design concept.

How this classification was reachedexpand
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.
