Any dataset here, as the library's Tabulated material (laalo3/chernova-2017).

# ... load laalo3 as above, then:
sim = ls.Simulation(
    particles=[ls.Particle(shape=ls.Sphere(radius_nm=50), material=laalo3)],
    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 LaAlO3 (Lanthanum aluminate)

Lanthanum aluminate, LaAlO3 (LAO), has been regarded as an ideal substrate material for epitaxial growth of 1-2-3 type superconducting thin films due to a close lattice match within 1 percent as well as its low dielectric constant and loss tangent compared to other common substrate materials.

Other names: Lanthanum aluminate, LAO
