Abstract


The field of nanoplasmonics has recently emerged as a result of the advances in understanding the nanoscale phenomena. The motivation is to understand how the light-matter interactions can be affected on the nanoscale by the presence of metal nanoparticles containing confined but still mobile electron gas. The variation of these electron densities by the optical fields results in the creation of highly enhanced local electric fields. The local fields further change optical properties of the nanomaterials (e.g., photon absorption and emission rates). The possibility to control such optical properties using precisely tailored metal nanostructures opens a variety of potential applications in new photonic and optical information processing devices, sensors, and biolabels. In this lectures, we will cover the basics of surface plasmon physics in nanostructured materials using semiclassical electrodynamic models as well as overview a number of important applications.
