The dispersion equation for surface plasmon-polariton (SPP) waves excited in a composite structure obtained by depositing a columnar thin film (CTF) on a metal (silver) substrate decorated periodically by an array of rectangular grooves was analyzed using rigorous coupled-wave approach. Only one solution of this dispersion equation is possible. The characteristics of the SPP wave are affected by the vapor incidence angle chosen to deposit the CTF.

Abstract
The dispersion equation for surface plasmon-polariton (SPP) waves excited in a composite structure obtained by depositing a columnar thin film (CTF) on a metal (silver) substrate decorated periodically by an array of rectangular grooves was analyzed using rigorous coupled-wave approach. Only one solution of this dispersion equation is possible. The characteristics of the SPP wave are affected by the vapor incidence angle chosen to deposit the CTF.File in questo prodotto:
