Dual‐to‐quad‐band evanescent‐mode substrate‐integrated waveguide band‐pass filters
Bibliographic record
Abstract
A new design methodology is presented for multi‐band evanescent‐mode band‐pass filters (BPFs) realisation by integrating substrate‐integrated waveguide structure with multiple short‐circuited irises. The electro magnetic (EM)‐behaviour of the distributed‐element structure is modelled with the lumped‐element equivalent circuit in a wide frequency range. Arbitrary transmission poles (TPs) and transmission zeros (TZs) corresponding to the different irises are characterised. Moreover, a rigorous prescribed filtering function is developed to design dual‐band evanescent‐mode BPFs in terms of independently tunable TPs and TZs. The proposed structure is reported to not only demonstrate miniaturised high quality‐factor dual‐band BPFs but also obviate the design challenges of multi‐band BPFs below the cut‐off frequency. Furthermore, two triple‐ and quadruple‐band evanescent‐mode BPFs are experimentally examined for the proposed concept verification.

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.
