Computational Nanoplasmonics

The basic idea of nanoplasmonics is to exploit the surface plasmon resonance - the interaction of electromagnetic radiation with a dielectric-to-metal interface - at the nanoscale. The small size of metal nanoparticles (normally much smaller than the wave length of the exciting light) allows for a very efficient plasmon resonance since all conduction electrons of the particle are excited in phase. The nanoparticles can be integrated in a variety of devices and serve, if excited, as a local source of strong coherent electromagnetic radiation. We are interested, e.g., in potential of these strong local fields in improvement of the solar cells performance, as well as in exploitation of coherent control possibilities in the near-field regime. We use finite-difference time-domain methodology to numerically propagate Maxwell's equations in time and space to obtain local information on generated enhancements of the incoming field.
