Load this data in Python, simulate in one more line

pip install lightsmith

# ... load pt as above, then:
sim = ls.Simulation(

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 Pt (Platinum)

Platinum (Pt) is a dense, malleable, and highly unreactive metal with a characteristic silvery-white appearance. It is one of the least reactive metals, showing significant resistance to corrosion, even at high temperatures. This makes it particularly valuable in industrial applications. Optically, platinum mirrors can be used in specialized optical instruments due to their durability and resistance to oxidation. Additionally, because of its inertness and ability to withstand high temperatures, platinum is commonly used as a substrate or material for thin-film deposition in various optical and electronic applications. In the broader industry, it's heavily used in catalytic converters for automobiles, in laboratory equipment, and in making jewelry due to its attractive appearance and resistance to tarnish.
