Accurate analysis of finite periodic substrate integrated waveguide structures and its applications
Bibliographic record
Abstract
In this paper, we present a systematic analysis of periodic structures based on substrate integrated waveguide (SIW) technology. In the periodic structures of interest, the unit cell is a circularly-shaped SIW section, which can be extended to any shape. In the beginning, the propagation constants of both even and odd modes of the SIW periodic structures are accurately extracted with the help of a numerical thru-line (TL) calibration technique, which utilizes two periodic structure sections having different cell numbers as calibration standards. Then, two design examples are showcased to validate the analysis results. The first example is a planar crossover structure using the circularly-shaped SIW coupling section. The other is a bandpass filter that is designed by making use of the stopband characteristics of the proposed SIW periodic structures. Good agreement is observed between simulation and measurement for both examples.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
