Load this data in Python, simulate in one more line

pip install lightsmith

import lightsmith as ls

# Pd-H (Palladium-hydrogen alloy, Palladium hydride): Palm et al. 2018: n,k 0.250–1.68 µm
pd_h = ls.fetch_refractiveindex("other", "Pd-H", "Palm", ref="c5c2f188e848453def5970e347399d653df2ffc2")
print(pd_h.range_nm)  # (250.02, 1684.53) nm
eps = pd_h.eps([633])  # complex permittivity

Downloads the original record once (pinned to the imported snapshot) and caches it.

Any dataset here, as the library's Tabulated material (pd-h/palm-2018).

# ... load pd_h as above, then:
sim = ls.Simulation(
    particles=[ls.Particle(shape=ls.Sphere(radius_nm=50), material=pd_h)],
    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"]).
