Metallic thin films and metallic nanoparticles give rise to peculiar optical effects in frequency regions where an external electromagnetic field can couple to charge oscillations resonantly. Plasmons localized at interfaces and closed surfaces give rise to huge local field enhancements which can be used for a great variety of applications based on linear and non-linear light-matter-interaction. Except for a few geometry-types an accurate modelling of plasmons and plasmon-related effects is feasible only by sophisticated numerics which combines reliability and efficiency, preferably. We report on FEM-based calculations for 3D metallic nanoparticles whith special emphasis on both test configurations as well as on effects in layered structures as they are typical for silicon solar cells.
