Miniaturized folded ridged half-mode substrate integrated waveguide
Bibliographic record
Abstract
Significant miniaturization of substrate integrated waveguides (SIW) is presented, utilizing folded techniques on ridged half-mode substrate integrated waveguide transmission lines. By moving the ridge structure inside the main waveguide channel, the transverse field distribution is wrapped around two substrate layers, achieving a miniaturization of 25.2% compared to ridged half-mode SIW, and 56.7% compared to half-mode SIW. The complex propagation constant of the folded ridged half-mode substrate integrated waveguide is extracted, showing negligible loss in performance compared to the ridged half-mode structure, and improved performance compared to conventional half-mode SIW. To verify performance experimentally, a folded ridge half-mode SIW is fabricated, and the measured scattering parameters are compared to simulation, with good agreement. To the best of the authors' knowledge, this work presents the first folded ridge half-mode SIW structure in the literature.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
