Extinction (blue curve), absorption (green) and scattering (red) efficiencies for optimized nanoparticles (Mie theory and linear polarization are used to evaluate (a)–(d), and DDA and circular polarization are used for (e)–(j)). The geometrical parameters (Figs. 2 and 4) of each optimized nanoparticle can be found in Tab. 1.
