In this example the optical activity of a chiral dimer of axi-symmetric nanoparticles is investigated. First, we visualise the parametrisation of such a dimer with the inter-particle separation, the dihedral angle, and one additional angle for each particle.

Cluster definition


The optical activity is modelled with full angular averaging over incident light directions. Scattering, absorption and extinction spectra are calculated for both right- and left-handed circular polarisations, and the difference corresponds to circular dichroism.
