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

Representative field across a layered material geometry.#

What is exercised#

Self-consistency of PhasorDetector broadband pulse vs CW monochromatic transmission through a 3-layer stack (ported from upstream FDTDX physics test). High-yield: sources, materials, phasors, PML — no FlexCredits.

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

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.
