Double Approach in the Investigation of Light Scattering by a Nickel Metal Cylinder

Abstract

In the present work, we have investigated the light scattering from a Nickel metal cylinder under normal incidence. A double approach using the Fresnel reflectance model and Lorenz-Mie approach shows that the Fresnel model cannot follow the changes in the scattering regime when the size parameter changes. Experiments show that, even for large cylinders, the Fresnel model overestimates the effects of reflection in the forward direction. The simulation using the Lorenz-Mie formalism shows that as the size parameter changes the scattering regime changes and for size parameter lower than one the distribution of light intensity tends to become uniform and, for size parameter equal or lower than 0.1 the distribution is uniform and independent on the scattering angle, with a strong polarization around 70%.
