Analysis of the periodic superconducting CPW transmission line with stepped-impedance for on-chip microwave filter applications
Bibliographic record
Abstract
This paper investigates the filter properties of a superconducting coplanar waveguide (CPW) periodically loaded with stepped-impedances. The unit cell of the steppedimpedance filter is a cascade of two transmission lines (TLs) with different characteristic impedances. This impedance difference is obtained by step changing on the width of the center strip of the CPW. We use the ABCD matrix representation together with the Floquet analysis to derive the dispersion relation of the infinitely long periodic structure. Scattering matrix analysis along with impedance calculation is performed for an arbitrary number of unit cells. Complex propagation constant, scattering parameters and the input impedance of the structure are expressed in a closed-form equations. The results display the low-pass filtering property. Also, the effect of changing geometrical parameters on the cut off frequency, rejection bandwidth and attenuation in rejection band of such a filter are shown and discussed in this paper.

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.
