Abstract


The Surface Plasmons Polaritons in a nanocavity are studied. It is shown that up to three SPPs can be obtained at a given frequency, one having a negative group velocity. A detailed analysis of the unfolding of the dispersion curve as a function of the width of the layer of metal is given.
