摘要

采用半解析边界离散化方法——辅助源法(MAS)对金属部件组成的光学天线进行了分析。由于光学天线表现出强烈的材料色散、损耗和等离子体极化效应，需要非常精确的数值模拟，因此导致了困难的数值问题。分析了带有球形纳米粒子的三维天线模型。这种结构在粒子间空间表现出很强的电场增强。

3D optical nano-antenna

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.
