Light scattering by a sphere dimer: Extinction cross section
Contact F. J. García de Abajo for details

Extinction (= light scattering + absorption) cross section of a sphere dimer, calculated from MESME (see F. J. García de Abajo, Phys. Rev. B 60, 6086 (1999)) up to an iteration order as specified below.
