Abstract

By using the finite element method (FEM) we have performed numerical analysis of the interference of the Surface Plasmon Polariton (SPP) excitation in the propagation of the electromagnetic field in a single mode dielectric waveguide. We observe that this interference can extinguish the mode in the waveguide core when electrodes are placed reasonably near of the dielectric waveguide. The transmission through the metal electrode waveguide is analyzed as a function of the electrode spacing.
