Use it in Lightsmith
Load this data in Python, simulate in one more line
pip install lightsmith
import lightsmith as ls
# TiN (Titanium nitride): Pflüger et al. 1984: n,k 0.031–2.48 µm
tin = ls.fetch_refractiveindex("main", "TiN", "Pfluger", ref="c5c2f188e848453def5970e347399d653df2ffc2")
print(tin.range_nm) # (31.07, 2479.7) nm
eps = tin.eps([633]) # complex permittivity
Downloads the original record once (pinned to the imported snapshot) and caches it.
import json, urllib.request
import lightsmith as ls
url = "https://materials.lightsmith.dev/v1/datasets/ds_989afc0f27dd/lightsmith"
tin = ls.Tabulated.model_validate(json.load(urllib.request.urlopen(url)))
print(tin.source) # citation and provenance travel with the data
Any dataset here, as the library's Tabulated material (tin/pfluger-1984).
# ... load tin as above, then:
sim = ls.Simulation(
particles=[ls.Particle(shape=ls.Sphere(radius_nm=50), material=tin)],
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"]).
Lightsmith is open source (MIT): Mie, T-matrix, BEM, DDA, FDTD, RCWA, TMM, mode solvers and inverse design behind one spec, on CPU or GPU. GitHub.
