# Neon Slab Datasets

Two related dataset releases from the Neon scalar dielectric slab benchmark.

## Contents

### `raw_scalar/`

The larger scalar slab dataset used for tabular surrogate experiments.

- `in_domain/`: main slab-family dataset with `dataset.csv`, `designs.csv`, `dataset_metadata.json`, generated configs, and reference cases
- `ood_probe/`: saved out-of-domain probe built from the same scalar slab family

These targets include the legacy proxy-normalized outputs and the benchmark-facing slab-normalized outputs recorded in the metadata.

### `benchmark_hybrid/`

The compact benchmark-facing dataset that matches the released Neon model.

- `in_domain/`: `hybrid_dataset.npz`, `samples.csv`, and `dataset_metadata.json`
- `ood_probe/`: benchmark-facing OOD probe in the same reduced centerline format

This is the right dataset family to use with the model at [Herrprofessor/Neon](https://huggingface.co/Herrprofessor/Neon).

## Scientific Scope

All files here come from the Neon scalar 2D frequency-domain Helmholtz benchmark for a rectangular dielectric slab at normal incidence in vacuum. These are benchmark-specific scalar data products, not general photonics datasets.

## Important Limits

- The scalar outputs are benchmark-facing only for the current lossless normal-incidence slab family.
- The hybrid data use a reduced centerline field representation and a 1D residual proxy, not the full 2D field.
- The OOD folders are degradation probes, not a claim of reliable extrapolation.
