Abstract:

Artificial chiral plasmonic nanostructure with strong circular dichroism (CD) has wide applications in biological monitoring, analytic chemistry, and optical property researching. In this paper, a tail is introduced to break the symmetry of metal spatial cross-shaped nanostructure to create chiral property. Finite element method calculating results show that dipole of upper tailed nanorod and that of bottom nanorod form Born–Kuhn model. CD effect depends strongly on the length and the orientation of introduced nanorod. This work provides novel way to generate tunable CD effect and provides potential application for further optimization.

Keywords:
