Load this data in Python, simulate in one more line

pip install lightsmith

import lightsmith as ls

print(hoya_taf2.range_nm)  # (365.01, 1013.98) nm
eps = hoya_taf2.eps([633])  # complex permittivity

# ... load hoya_taf2 as above, then:
sim = ls.Simulation(
    particles=[ls.Particle(shape=ls.Sphere(radius_nm=50), material=hoya_taf2)],
    medium_index=1.0,
    wavelengths=ls.WavelengthRange(start_nm=400, stop_nm=1000, num=81),

res = ls.solve(sim)  # exact Mie for a sphere
print(res.q_ext)     # extinction efficiency at each wavelength

Same spec runs with DDA, FDTD, BEM or T-matrix: ls.compare(sim, ["mie", "dda"]).
