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

# ... load rbcl as above, then:
sim = ls.Simulation(
    particles=[ls.Particle(shape=ls.Sphere(radius_nm=50), material=rbcl)],
    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 RbCl (Rubidium chloride)

Rubidium chloride (RbCl) is a white crystalline compound composed of rubidium cations (Rb⁺) and chloride anions (Cl^-). It is highly soluble in water, producing a neutral solution. RbCl is commonly used in laboratories, especially in biochemical research as a source of rubidium ions, which have been used in various physiological studies. The compound shares many properties with other alkali metal chlorides, such as high solubility in water and a hygroscopic nature. It also has potential use in some optical and electronic applications. Due to its reactivity, especially with moisture, precautions should be taken when handling and storing this compound.
