标题： Fourier microscopy of single plasmonic scatterers

摘要： 我们报告了一种新的实验技术，用于量化由单个等离子体和超材料纳米散射体散射的光的角分布，该技术基于暗场共聚焦设置中的傅里叶显微镜。 这种新的设置是量化单个等离子体和超材料基本单元以及这些单元的小型耦合簇的散射特性的必要工具，这些单元被认为是纳米天线、光捕获结构和变换光学的主要成分。 我们展示了一系列不同长度的金纳米线的测量结果，并说明单个金纳米线的辐射模式如何随着线长以及驱动极化和波矢的变化而变化。 显示英文摘要

摘要： We report a new experimental technique for quantifying the angular distribution of light scattered by single plasmonic and metamaterial nanoscatterers, based on Fourier microscopy in a dark field confocal set up. This new set up is a necessary tool for quantifying the scattering properties of single plasmonic and meatamaterial building blocks, as well as small coupled clusters of such building blocks, which are expected to be the main ingredients of nano-antennas, light harvesting structures and transformation optics. We present a set of measurements on Au nanowires of different lengths and show how the radiation pattern of single Au nanowires evolve with wire length and as a function of driving polarization and wave vector.
