This widget allows you to calculate the optical cross-sections [extinction (Q_ext), scattering (Q_scat), and absorption (Q_abs)] of a homogeneous, isotropic, and spherical nanoparticle placed in a homogeneous medium using Mie scattering formalism.
Q_ext, Q_sca, and Q_abs are the efficiencies normalized to the physical cross-section πR² of the nanoparticle.
