Abstract
This article presents a systematic and an efficient synthesis technique for designing single-band and dual-band waveguide (WG) filters with transmission zeros (TZs). The proposed electro-magnetic (EM)-based synthesis technique directly results in a filter design with an RF performance that is in excellent agreement with the ideal filter performance, thus significantly reducing the post fine optimization effort. Furthermore, the proposed technique also reduces the EM simulation resources required for the filter synthesis. The synthesis technique is lucidly explained by designing a symmetrical 6th-order WG filter with four TZs, a 9th-order filter with three asymmetric TZs and a 6th-order dual-band filter. To the best of the author’s knowledge, this is the first filter synthesis technique, which can be adopted to design WG filters, including TZs with minimum or no post fine optimization.

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
