方形劈裂环-方形环结构中磁法诺共振的产生及操控
Generation and manipulation of magnetic fano resonance in square spilt ring-square ring system
摘要
Abstract
The optical property of the square spilt ring-square ring (SSR-SR) is simulated and an-alyzed by finite element method (FEM ) and plasmon hybridization theory (PHT ) in the range of visual light .The simulated results show that the bright modes of the spilt square ring couple with the dark modes of the square ring ,which leading to magnetic Fano resonance .The linetype of the magnetic Fano resonance can be manipulated by changing the geometry parameters of the nano -structure .Furthermore ,the SSR-SR structure is very sensitive to the surrounding environment refractive index .The calculated result exhibits that the maximum refractive index sensitivity ex -ceeds 1650 nm/RIU and the maximum figure of merit (FOM ) reaches 26 .02 .关键词
