Dual-Band Unit Cell of EBG Structure for Printed Gap Waveguide
Bibliographic record
Abstract
A dual electromagnetic gap (EBG) is realized by a unit cell of three substrates sandwiched between two metal plates. The unit cell consists of two stacked dielectric substrates topped by an aired substrate below the top metallic plate. The unit cell consists of a large mushroom patch on the bottom grounded substrate etched on its top and connected to the lower metal plane by a conducting via. The intermediate substrate has four smaller mushroom patches of total size smaller or equal to the bottom patch, and each is connected to the lower patch by conducting vias. The total size of the one-unit cell is 1.8mm. The unit cell is designed to achieve two stop band gaps; one is for the lower band for 13–24 GHz and another for the upper band 34–44 GHz. Inserting a so-called printed ridge perturbing the periodicity creates propagating modes within the EBG bands, guiding the electromagnetic waves between the upper conductor and the ridge and suppressing them elsewhere. The simulated results are presented. They could have the potential to be used for various dual-band applications.

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.
