Computer simulation of nanoplasmonic antennas

Plasmoinc structures, in particularly plasmonic nano antennas are very attractive in many applications. From other side numerical simulations of plasmonic structures are very demanding and expensive in terms of memory and CPU time, making the selection of a suitable numerical method for the field computation important. The numerical problems are caused because optical nanostructures based on metal parts exhibit strong material dispersion, loss, and plasmon-polariton effects that require a very accurate numerical simulation. We use new design concepts based on 3D simulations for nanoplasmonic antenna structures by using MAS, which is the semi-analytic Maxwell solver for computational electrodynamics in the frequency domain and can handle various electromagnetic (EM) problems on the personal computers while.
