PLASMONIC PROPERTIES AND OPTICAL ACTIVITY OF A THREE-DIMENSIONAL SIX-BLADE WINDMILL NANOSTRUCTURE
Abstract
Two exchangeable LSPR modes with different coupling field are observed in calculating magnetic field intensity in accordance with adjusting geometrical parameters. Compared with planar nanostructures, three-dimensional windmills show stronger optical activity, and the maximum value of the asymmetry g-factor was 0.6. The numerical simulation results in this paper also contain the optimal geometrical parameters to achieve the best circular dichroism effect at different resonance modes. The results give a contribution to the design of novel chiral optical nanostructures.
