| Summary: | In this research, the surface plasmon-polariton modes at interface of a metal and a polygonal chiral thin film in Kretschman configuration theoretically have been studied. With depiction of optical absorption spectra for P-linear polarized incident light, the surface plasmonic modes from the waveguide modes have been distinguished. The effect of structural parameters such as the thickness of polygonal chiral thin film, the thickness of metallic thin film and the growth angle of chiral columns on the propagation of plasmonic modes has been investigated. The results showd that more than one plasmonic mode can be excited at interface of a polygonal chiral thin film and a metal. |
