Short-circuit equivalence between rectangular waveguides of regular sidewalls (rectangular waveguide) and sidewalls of cylinders (substrate-integrated rectangular waveguides), plus its extension to cavity
Bibliographic record
Abstract
Substrate-integrated rectangular waveguide (SIW) is a rectangular waveguide (RW) with two sidewalls of cylinders (vias) instead of solid walls connecting the solid wall of the top and bottom plates. An equivalence formula between their widths has been derived based on the work by Che et al., 2005 [2005 Asia-Pacific Microwave Conference, Suzhou, China, December 4–7, 2005, pp. 296–299]. The authors have derived the equivalence formula between the locations of the corresponding short circuits by cylinder walls and by the solid wall. An extension of latter is the equivalence between resonance cavities of SIW and RW. Such equivalences are convenient for the design of small waveguides, of millimeter wave, in a multilayer circuit structure, such as the low-temperature co-fired ceramic. Some numerical simulations and experiments have been carried out to demonstrate the validity of the proposed approaches.

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.
