Abstract
Substrate integrated waveguides (SIWs) have huge potential for the development of microwave and millimeter-wave components in modern communication devices. Herein, a novel approach based on the vacuum suction of conductive polymer is introduced to substitute classical Cu electroplating technique for the simple and rapid metallization of conductive vias embedded in the dielectric substrate. Various combinations of vacuum level and vacuum duration are tested on vias with different geometries. Meaningfully, with the proper control of these two parameters, the specific partial height via becomes achievable in a single-layer substrate. As a proof of concept, two bandstop SIW filters based on the partial height via resonator are developed in a self-made flexible substrate and a commercial rigid laminate. Relatively good agreement can be seen between the measured and simulated results of their reflection coefficients and resonant frequencies, which confirm the reliability and robustness of this approach for the future SIW development.

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
