Any dataset here, as the library's Tabulated material (mgo/stephens-malitson-1952).

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

About MgO (Magnesium monoxide)

Magnesium oxide (MgO) is a white solid that exhibits refractory and insulating properties. It's commonly used in the ceramics industry and for producing crucibles. In thin film form, MgO serves as an excellent substrate for the growth of high-quality epitaxial films and is transparent in the ultraviolet to infrared regions, making it suitable for various optical applications. Mineral: Periclase

Other names: Magnesium monoxide, Magnesia, Magnesium(II) oxide, Magnesium oxide, Periclase
