Calculation of complex propagation constants of Surface Plasmon Polariton rectangular waveguide by the Method of Lines
In this paper, we present the numerical study about the complex propagation constants of SPP rectangular waveguide by the method of lines (MoL) with high accuracy. We calculate the dependences of complex propagation constants on the waveguide sizes and wavelength. The fundamental, important and interesting characteristics of SPP rectangular waveguide have been revealed.
