Modelling light propagation in plasmonic nanostructures

Using advanced mathematical techniques for optical computing and combining them with advanced optical engineering techniques and understanding of physical and chemical processes in plasmonic materials we developed novel boundary integral equation based numerical simulation tool. The performances of numerical simulation tool were investigated by means of extensive numerical studies of plasmonic nanostuctures including nanostructures with periodically and aperiodically spaced nanoparticles embedded in homogenenous medium, isolated homogeneous, layered and multilayered plasmonic nanoparticles. Selecting the most pormissing particle configurations, we applied the most efficient hierarchical method to reduce the complexity of calculation schemes for each particular nanostructure configuration.
