Abstract Based on the theoretical model and the numerical simulation method, by setting the certain values of saturation parameter, propagation constant and guiding parameter the localized surface waves are formed at the interface between linear dielectric and photorefractive crystals. Through changing the value of the free parameter, we can get the localized surface modes and the waveform of the localized surface waves. Study results show that: The smaller the propagation constant, the slower the localized surface wave attenuation in the photorefractive crystals and the linear dielectric medium. The essential cause for the formation of the localized surface waves is the diffusion mechanism, which ensures attenuation from the surface to the bulk of the medium, and restricts beam energy in the narrow surface layer. We stimulated the propagation of the localized surface waves without perturbation at the medium interface using the split-step Fourier transform method. The stability of the localized surface waves in the propagation process is verified.

Key words： The localized surface waves stability the split-step fourier transform method
