Spectral properties of chiral electromagnetic near fields created by chiral plasmonic nanostructures

摘要

We investigate relations between near field and far field polarization characteristics of thechiral plasmonic nanostructures, using electromagnetic simulations. We found that the spectralfeatures of chiral near fields created by the nanostructures intercorrelate with those of far fieldoptical rotation. This finding may provide us a method to characterize the chiral near field.
