Load this data in Python, simulate in one more line

pip install lightsmith

import lightsmith as ls

# AMTIR-3 (out of production) (AMI): AMTIR-3 (out of production)
ami_amtir_3 = ls.fetch_refractiveindex("specs", "AMI-infrared", "AMTIR-3", ref="c5c2f188e848453def5970e347399d653df2ffc2")
print(ami_amtir_3.range_nm)  # (3000, 14000) nm
eps = ami_amtir_3.eps([6480])  # complex permittivity

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

print(ami_amtir_3.source)  # citation and provenance travel with the data

Any dataset here, as the library's Tabulated material (ami-amtir-3/ami).

# ... load ami_amtir_3 as above, then:
sim = ls.Simulation(
    particles=[ls.Particle(shape=ls.Sphere(radius_nm=50), material=ami_amtir_3)],
    medium_index=1.0,
    wavelengths=ls.WavelengthRange(start_nm=3000, stop_nm=14000, 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"]).
