Realistic Air-Filled TEM Printed Parallel-Plate Waveguide Based on Ridge Gap Waveguide
Bibliographic record
Abstract
A double-ridge and double-sided textured surface waveguide based on the printed ridge gap waveguide (PRGW) is introduced. The structure acts as a parallel-plate waveguide supporting TEM waves, and it is referred to as TEM-PRGW. The TEM-PRGW has lower insertion loss and more confined power around the double ridges in comparison with the single-textured PRGW. The characteristic impedance of the TEM-PRGW is extracted from the conventional parallel-plate impedance expression. The TEM-PRGW is symmetric around the middle horizontal line splitting the gap. The modified unit cells of the periodic structure around the double ridges are also introduced to improve the TEM-PRGW performance in the presence of any discontinuities along the propagating direction, which might excite undesired horizontal polarization. Prototypes of the straight and double bend lines are fabricated based on the modified unit cells to prove the concept and have confidence in the simulation results.

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.
