Mie light scattering by a single sphere: Extinction cross section
  

Extinction (= light scattering + absorption) cross section of an individual sphere.
For details, see for example V. Myroshnychenko et al., Chem. Soc. Rev. 37, 1792 (2008).


Dielectric function ε(ω)

For Drude:
ε(ω)=εb+ωp2/[ωg2-ω(ω+iη)]
εb =
ωp (eV) =
ωg (eV) =
