Paper Abstract

A sculptured nematic thin film (SNTF) is an assembly of parallel nanowires that bend in a fixed plane orthogonal to the substrate on which the film is deposited. The absorbances, reflectances, and transmittances of linearly polarized, obliquely incident light were calculated for a planar SNTF-metal interface in the Kretschmann configuration. Empirical data on aluminum for the metal and titanium-oxide SNTFs were used for the calculations. The solution of the boundary-value problem for the Kretschmann configuration revealed that more than one surface-plasmon-polariton (SPP) waves can be excited at the planar interface of a thin metal film and an SNTF.
