摘　　要：八木结构的纳米光学天线在量子信息技术、高密度数据存储和光学等领域有着广泛应用。探讨基于贵金属Au的三层纳米八木天线的远场特性,重点研究不同位置的极子点对其远场特性的影响,并用COMSOL仿真软件计算出它们的远场辐射特性,设计出性能优越的纳米光学天线,通过改变极子点的位置可以使多极共振位置的移动具有显著的可调谐性。The Yagi nano-optical antenna has a wide range of applications in the fields of quantum information technology,high-density data storage and optics.This paper discusses the far-field characteristics of a three-layer Yagi nano-antenna based on noble metal Au.Among them,the influence of the different position of the pole points on its far-field characteristics is mainly studied.The far-field radiation characteristics are calculated by COMSOL simulation software in order to design a nano optical antenna which the performance is superior.It is found that the movement of the multipole resonant position can be significantly tunable by changing the position of the pole point.
