- Abstract
- Numerical models of the optical properties of a single nanowire are essential for reproducing the results of the measurements and understanding the optical processes. Intuitively, the properties of a single finitely long nanowire would converge to the ones for an infinitely long nanowire if it is long enough. However, the simulations show that the scattering cross section per unit length of a finitely long nanowire is better approximated by the cross section per unit length of another finitely long wire with a different length than by an infinitely long nanowire, which reduces the degrees of freedom by one. The results regarding the infinitely long nanowires were based on Mie scattering, while the ones concerning the finitely long... (More)
