Abstract
Bandstop filters in microstrip technology are introduced. The filters are based on a T-shaped resonator located between two identical L-shaped resonators; all of them are coupled to a main microstrip line, and separated by sections of transmission lines with appropriate length. According to ABCD matrix analysis, carried out for commensurate resonators, this structure produces two transmission zeros in the stopband as well as three reflection zeros in the passbands. X-band and Ku-band bandstop filters are designed based on the proposed method with bandwidths of 1.06 GHz and 0.97 GHz at mid-band frequencies of 9.72 GHz and 14.77 GHz, respectively. Both filters are prototyped and measured. Good agreement between simulated and measured results demonstrates the reliability and robustness of the design method.

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
