Abstract:
In report is made the synthesis of the surface plasmon polariton propagation phenomenon.
Methods such as Maxwell equations, Drude model used to describe the light confinement at the interface
between two media are analyzed. Simulation techniques such as the transfer matrix formalism and the
dispersion equation are examined. Finally are presented the results of our own investigations aiming
plasmonic structure containing a film of amorphous chalcogenide material. It is shown the structure is very
sensitive to the modifications of the refractive index that may be used for the design of the optical memory.
