Any dataset here, as the library's Tabulated material (licl/li-1976).

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

A dispersive Drude–Lorentz model for time-domain solvers.

About LiCl (Lithium chloride)

Lithium chloride (LiCl) is a salt with a range of applications, from hygroscopic uses in air conditioning and industrial drying to a role as a brazing flux for aluminum in metallurgy. In the realm of optics, lithium chloride is employed as a crystal for IR, THz, and far-IR spectroscopy. It has a broad transmission range and is relatively inert, making it useful for specialized applications that require transparency in those wavelength ranges. However, it is highly hygroscopic and must be carefully handled and stored to maintain its optical properties.
