Theoritical description of Surface Plasmons Polaritons — •Benhayoun Othmane — Universität Kassel, Kassel, Germany

Surface plasmons-polaritons (SPPs) are collective electronic excitations existing at the metal-dielectric interface, created under certain conditions, by the interaction of surface plasmons in the metal and an incident light. Using merely Maxwell*s equations, one can, with an appropriate ansatz, deduce some qualitative properties of SPPs, such as their wavelength, propagation length and penetration depth into both the dielectric and the metal. However not much is known about how they transfer energy to the lattice, their interaction with light or their damping process. Here we use, as was made by Ritchie [1], a hydrodynamical approximation modeling the surface plasmons interacting with a laser source, in order to attempt answering these questions.
