Abstract
This article presents a novel broadband transition from coaxial line to substrate-integrated waveguide (SIW). The SIW wall includes three rows of metallic vias, where the vias of smaller diameter are squeezed between vias of larger diameter. This modification results in a corrugated via-wall SIW (CVWSIW) providing lower loss. Three versions of stubs (rectangular, semicircular, and triangular) are designed around the coaxial line launch on the top metal plane of the SIW. All transition versions are fabricated and tested, and the measurement results are in a good agreement with simulations. The measured more than 14-dB return loss (RL) and fractional bandwidth (FBW) of 75%, 79.4%, and 44.6% (10-dB FBW: 97.14%, 90.5%, and 78.26%) in these versions for the 9–26-GHz frequency range were obtained, respectively. The insertion loss (IL) is less than 0.63, 0.91, and 0.68 dB; the total loss is below 20%, 30%, and 25% for these versions for the same frequency band, respectively.

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
