Bibliographic record
Abstract
Prof. Mojgan Daneshmand made seminal contributions to the advancements of substrate integrated waveguide (SIW) technology together with her students and colleagues. In this paper, we present our recent work on miniaturized SIW diplexer in memory of Mojgan and her family. The proposed diplexer is centered at 3.45 and 4.9 GHz for 5G sub-6 GHz communications, which is enabled by a common dual half-mode substrate integrated rectangular cavity (HMSIRC) coupled with singlemode cavities in each channel. Besides the elimination of T-junction, HMSIRCs are also introduced for the miniaturization of sub-6 GHz circuits. Additionally, by employing the first two modes in the dual-HMSIRC, a large frequency ratio of 1.42 between 3.45 and 4.9 GHz can be realized, which is difficult to implement with the original whole cavity scheme because of spurious passband problems. A 2nd-order example with ripple fractional bandwidths of 2% and 1.6% for the two channels is synthesized, designed, fabricated, and tested for demonstration.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
