Abstract
A novel approach to achieving microwave frequency multiplication with a continuously tunable multiplication factor using an unbalanced temporal pulse shaping (TPS) system is proposed and demonstrated. The proposed TPS system consists of a Mach-Zehnder modulator and two dispersive elements having opposite dispersion values. Since the values of dispersion are not identical in magnitude, the entire system can be considered as a typical balanced TPS system for a real-time Fourier transformation followed by a residual dispersive element for a second real-time Fourier transformation. The microwave frequency multiplication factor is determined by the dispersion values of the two dispersive elements and can be continuously tunable by changing the values. Numerical simulations and experiments are performed. Microwave frequency multiplication with a factor as high as 13.2 is experimentally demonstrated.

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
