Abstract

fetched live from OpenAlex

This paper presents a microstrip ring resonator design which exhibits suppressed harmonic excitation and high quality factor. The resonator is constructed from four quarter-wave coupled-line couplers, connected in a square configuration. Of interest is the change in the frequency response of the ring when corrugated couplers are used in place of ordinary couplers. By direct comparison it is shown that the use of corrugated couplers in the construction of the ring results in an increase in quality factor from 34 to 47, and 30 dB rejection of the first harmonic, at the expense of a 1.5 dB increase in insertion loss and a reduction in harmonic frequency from 2.858 GHz to 2.701 GHz.

Not 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.
