3D optical nano-antenna

Abstract

A semi-analytic boundary discretization method, the Method of Auxiliary Sources (MAS) is used to analyze Optical Antennas consisting of metallic parts. It is demonstrated that difficult numerical problems are caused because optical antennas exhibit strong material dispersion, loss, and plasmon-polariton effects that require a very accurate numerical simulation. The 3D antenna model with spherical nano particles is analyzed. This structure exhibits a strong enhancement of the electric field in the space between particles.
