Abstract
This letter presents a novel and challenging design of a 50-way all-waveguide W-band radial combiner, utilizing WR10 ports for all connections. The novelty lies in its pioneering design and implementation of the radial combiner structure, while the challenges stem from the complexities associated with high-frequency design, manufacturing precision, and the integration of multiple waveguide sections. The design begins with a radial combiner featuring rectangular waveguide peripheral ports and a circular waveguide intermediate port operating in the TE<sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">01</sub> mode, which is particularly advantageous due to its low loss, attributed to its field distribution with minimal surface current density. A mode transducer is designed to convert the intermediate circular waveguide TE<sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">01</sub> mode to the dominant TE<sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</sub> mode in the WR10 rectangular waveguide. This transducer is integrated with the radial combiner to produce a standard WR10 waveguide output. The design follows a modular approach, dividing the process into separate optimally designed blocks, which are then integrated to form the final structure. Mechanical considerations are crucial at such high frequencies, and all features, such as matching disks and bifurcations, are designed to require only simple mechanical tooling. The design is thoroughly discussed, and an experimental prototype was fabricated and tested, demonstrating good performance without the need for tuning.

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
