Novel Photonic Crystal slow wave structures for sub-mm/THz wave-generation application
Bibliographic record
Abstract
An all metallic Axial load Double Defected-Photonic Crystal (ADD-PC) with a cylindrical beam channel, suitable for use as a Slow Wave Structure (SWS) in Cherenkov radiation-based oscillator/amplifier, is introduced. The design of a metallic SWS high power millimeter/THz source, with a superior thermal conductivity and the dimensions, which are full realizable using existing fabrication technique, is presented. Proceeding from the band diagram, the dispersion properties and modal phase velocity of the proposed SWS are calculated. Employing a 3D printing technology and metallic coating, a scaled prototype of the proposed SWS was fabricated. Using the resonance method and a custom built probe-wheel radiator, the cold test of the SWS was performed. The scattering parameters results are in a good agreement with the theoretical predication for the slow wave propagation.

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.
