MAS simulation of plasmon coupling in nanosphere pairs

Plasmonic structures 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. To examine this problem, we applied Method of Auxiliary Sources (MAS) to a group of 3D plasmonic nanoshpere problems.
