摘要：

In this paper, we present a chiral hollowed-out split ring resonators nano structure. This novel chiral nano structure can form multiple electric dipoles and magnetic dipoles in infrared and visible regions. And the interaction of these dipoles caused optical activities and multi-band negative refractive index. The appropriate geometric parameters are obtained through optimization and analysis of this structure. Circular dichroism, polarization azimuthal rotation angle, ellipticity, refractive index and chiral parameter are calculated using S-parameter retrieval method, and these optical properties can be tunable by the geometric parameters of the chiral structure. This chiral structure metamaterial would offer electromagnetic applications in the infrared and visible regions, for fields like imaging, invisibility cloak and perfect lensing.
