Abstract
In this paper, a finite difference frequency domain (FDFD) method is used to analyze a new class of substrate integrated waveguides (SIW) that are formed by using periodic metallic slots instead of metallic vias. When the gaps between slots are small enough, the broadside dimension of their equivalent rectangular waveguide is approximately equal to the spacing between inner walls of the slots. This means that the design of substrate integrated waveguide circuits (a family of substrate integrated circuits or SICs) such as resonators and filters based on the SIW concept can greatly be simplified. A new FDFD algorithm is proposed to analyze the substrate integrated waveguide resonators. Combining with a perfectly matched layer (PML) technique, the FDFD algorithm based on Maxwell's equations is extended and can be used to analyze open resonant problems.

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 it
