Infinite 3D printed microstructured low-loss and near-zero dispersion polypropylene fiber for THz communications
Bibliographic record
Abstract
In this work, a low-loss near-zero dispersion polypropylene fiber is designed for signal transmission at the carrier frequency of 128 GHz. An infinite 3D printing technique is explored to continuously fabricate the proposed fiber without length-limit. The in-depth theoretical and experimental comparisons between the two fibers printed using standard and infinite 3D printers are introduced in detail. Particularly, transmission losses of 2.39 dB/m and 5.57 dB/m have been experimentally demonstrated for the two fibers at 128 GHz. Furthermore, for the two fibers with the corresponding lengths of 2 m and 1.6 m, signal transmission with bit error rates far below the forward error correction limit (10-3) was clearly observed. Error-free transmission is realized at the bit rates up to 5.2 Gbps for the standard 3D printed fiber at the length of 1.5 m.

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.
