This case checks the implementation against an analytical identity, convergence property, or independent physics invariant.

## What is exercised

Upstream solver/tests/simulation/physics/sources/test_dipole_radiation.py

This case runs at its declared full benchmark resolution (resolution factor 1.0).



## Recorded result

| Metric | Observed / error | Reference / limit | Error | Effective budget | Result |
|---|---:|---:|---:|---:|---:|
| `pytest_exit` | 0 | 0 | 0 | — | <span class="metric-pass">PASS</span> |

The table is rendered from `progress.json`; it is not a hand-written success claim. For metrics that report an error directly, the “observed” column repeats that error and the reference column is the acceptance threshold.

## Reproduce

```bash
uv run fdtdx-bench run --case analytical_dipole_radiation
```

Implementation and provenance: `benchmarks/cases/analytical_dipole_radiation/case.yaml`, `benchmarks/cases/analytical_dipole_radiation/run.py`.
