Analytical Q
FDTD confirmation Q
Q vs accepted optimization step (log scale).
FDTD mode intensity
Waiting for FDTD field data…
Parameter change vs seed (current geometry)
Gap Δ (nm) — solid
Mean radius Δ (nm) — dashed · ½(Δrx+Δry)
Ellipticity Δ (nm) — dotted · Δ|rx−ry|
Hole index 0 = center-most pair of the N=15 taper. Values are current geometry minus seed.
