Investigation on the optical resonance and near field effects of a 2D periodic dielectric spheres on metallic surfaces by combining theoretical calculations with experimental studies were carried out. The light scattering and coupling was numerically studied. Nanostructures were fabricated on the metallic surfaces using these arrays of micro- and nano-spheres with a single laser pulse (KrF, λ=248 nm). The occurrence of such nanostructures is well explained by the theoretical calculations. The results can be useful in investigation and development of spheres-assisted nano-patterning.
