Abstract
We present an enhanced design - in terms of resolution flexibility, input port position arbitrariness, and frequency range and resolution tunability - of the planar Rotman lens spectrum decomposer (RL-SD). The resolution flexibility enhancement consists in allowing different frequency sampling functions (decreasing, uniform, and increasing) by properly distributing the output port locations along the frequency-position law of the RL-SD. The input port position arbitrariness is realized by adding a calibration array compensating for the frequency deviation induced by the input modification. The frequency range and resolution tunability is achieved by electronic port switching. A complete design procedure is provided and two enhanced RL-SD prototypes, with uniform port distribution and uniform frequency resolution, respectively, are numerically and 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
