摘要

运用有限元法（FEM）和等离激元杂化理论（PHT）模拟并分析了劈裂方环（SSR）纳米结构和劈裂方环二聚体的消光特性。模拟结果显示，劈裂方环的偶极模式出现环流且磁场增强强度达到39.5。通过引入对称性破缺，劈裂方环二聚体的消光谱中出现新的共振模式且形成不对称的Fano线形。Fano线形可以通过改变劈裂方环二聚体的几何参数和排列方式进行调控。基于劈裂方环二聚体的这些性质，可以将其应用于光开关和表面增强光谱学领域中，也可作为基于磁Fano共振器件中的元件。

Abstract

The extinction characteristics of the spilt square ring （SSR） nanostructure and the split square ring dimer are simulated and analyzed by finite element method （FEM） and the plasmon hybridization theory （PHT） . The simulated results show that the dipole mode of the split square ring appears circular current and the magnetic field intensity attains a value of 39.5. Through the introduction of symmetry breaking

a new resonance mode and an asymmetric Fano line-type appear in the extinction spectrum of the split square ring dimer. Fano line-type can be manipulated by changing the geometric parameters and arrangement of the split square ring dimer. Based on these properties of the split square ring dimer

they can be used in the field of optical switching and surface-enhanced spectroscopy as well as a functional component in magnetic Fano resonance-based devices.
