Characteristics of Plasmonic at a Metal/Chiral Sculptured Thin Film Interface

Abstract

The propagation of surface plasmon polariton at an interface of metallic thin film and chiral sculptured thin film theoretically has been investigated using the transfer matrix method in the Kretschman configuration. The optical absorption of structure as a function of polar incident angle for linear polarization P and S has been calculated at different structural parameters.The results show that exist multiple plasmon peaks for P-polarization, while there are the weak plasmon peaks when incident of light is S-polarized plane wave.

Excitation of Surface Plasmon-Polariton Wave at Both Interfaces of a Silver Thin Film in Two-Layer Kretschmann Geometry

“…With the emergence of the new generation of thin films called sculptured thin films (STFs), the studies on SPP excitation at the interface of metal and anisotropic dielectric has increased [7][8][9][10][11][12][13][14].…”

Excitation of Multiple Surface Plasmon-Polaritons by a Metal Layer Inserted in an Equichiral Sculptured Thin Film

“…It is seen that the values of SPP peaks in absorption are coincident on the values of SPP troughs in reflection. Therefore, the existence of a sharp peak in optical absorption versus θinc with linear polarization indicates to excitation a SPP wave which is equivalent with a sharp trough in reflection spectra without a compensatory peak in transmission plot [27][28][29].…”

Localized surface plasmons of a single ambichiral nanostructure

“…The SP resonance of the Cu nanowires and two-segmented Au-Cu nanowires embedded in a polycarbonate membrane has been reported [20,21]. The propagation SP-polariton at interface of metal and chiral sculptured thin films has been studied by us [22].…”
