Q versus accepted boundary step
Blue: tracked-pole FEM Q. Gold circles: qualified Tidy3D checkpoints.
Geometry · matched axes
Initial complete-material level set: 40 holes plus the straight outer sidewalls.
Current accepted hole-and-sidewall checkpoint, same axes and legend.
Layer cross-section: SiO₂ / patterned Si₃N₄ / anthracene / PVA / air.
Most recent diagnostic FDTD field
XY midplane, Hann-projected resonant vector |E|²; robust per-panel scale.
XZ midplane, same resonance and temporal projection.
Before the first new diagnostic, these panels show the FDTD-qualified launch seed.
