Investigation of the optical Properties and plasmonic oscillations of nano-structure of Manganese Chiral Single Ring

Manganese chiral single ring nanostructure are produced using oblique angle deposition together with rotation of substrate holder about its surface normal. The structural characterization of the produced samples was obtained using field emission scanning electron microscope (FESEM) and atomic force microscope (AFM). The optical spectra of the samples were obtained using a single beam spectrophotometer for the incident light of the surface normal. Then, absorption spectra are obtained for linearly polarized different azimuthal angles by homogenization method. Obtained results are consistent with the experimental optical absorption spectra. The plasmonic oscillations type inside nanostructure of chiral single ring is investigated by using the discrete dipole approximation (DDA).
