Public input and output contract

Inputs

  • calibration_samples.csv (data): Calibration-sample metadata including paired-nanorod geometry, substrate flag, spacer thickness, and effective slab thickness.
  • calibration_optics.csv (data): Wavelength-resolved transmission/reflection amplitudes and phases for the calibration samples.
  • heldout_samples.csv (data): Metadata for unseen paired-nanorod samples whose optical response and retrieved bands must be predicted.
  • retrieval_notes.md (text): Observable definitions, sign conventions, output schemas, and allowed candidate mechanism labels.

Outputs

  • analysis.py (code): Agent-authored retrieval and model-selection workflow.
  • results/calibration_retrieval.csv (data): Retrieved effective optical quantities for calibration samples versus wavelength.
  • results/model_comparison.csv (data): Comparison of candidate mechanism families with calibration and validation metrics.
  • results/heldout_prediction.csv (data): Predicted held-out optical observables and retrieved effective quantities versus wavelength.
  • results/negative_index_summary.csv (data): Per-sample summary of negative-index windows and minimum retrieved real refractive index.
  • results/retrieval_diagnostics.png (figure): Diagnostic figure showing representative spectra, retrieval curves, and held-out transfer behavior.
  • results/conclusion.txt (conclusion): Short scientific conclusion stating whether the data support a negative-index band and which compact mechanism family best explains it.
