Dual-Layer Slow-Wave Half-Mode Substrate Integrated Waveguide E-Plane Coupler
Bibliographic record
Abstract
In this brief, an ultra-compact broad wall coupler based on slow-wave half-mode substrate integrated waveguide (SW-HMSIW) is presented. The E-plane coupling between different layers of circuits under slow-wave effect is studied for the first time. The slow-wave construction is realized by complementary split ring resonator (CSRR) loaded HMSIW. Moreover, CSRRs could serve as coupling sections at the same time. Hence, the slow-wave effect and energy coupling can support each other and operate well together simultaneously. Furthermore, the slow-wave effect could enhance the coupling level of each aperture and realize coupler size reduction in general. As a result, the presented coupler can operate in a wide band (45%) with 50% size reduction comparing to typical HMSIW fast-wave one, which would be suitable for applications in six-port circuit and Butler matrix with strict size and performance requirements. Simulated results are in good agreement with measured data.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
