各向异性电介质对纳米壳层结构的法诺共振调制
Adjusting Fano resonance of core-shell nanostructure with anisotropic dielectric material
摘要
Abstract
Fano resonance has broad applications in optical switching,chemical and biological tagging and in the design of ensing devices.Due to the effect of anisotropic dielectric material on scattering property of nanostructures,we propose to adjust Fano resonance of core-shell nanostructure by anisotropic dielectric material.First,the general condition of forming Fano resource with core-shell sub-wavelength structure is derived from Mie scattering theory.Analysis indicates that changing the radial or tangential component of permittivity can adjust Fano resonance by resonance wavelength,peak intensity and shape of scattering curve.This work promotes the application of Fano resonance.Numerical calculations demonstrate the feasibility of our theoretic analysis.关键词
