Research of the surface wave at the interface between the photorefractive crystal and the linear dielectric medium

In the aspect of the particle oscillator model, through simulating numerically the low amplitude delocalized, shock, and localized surface waves at the interface, we find that for the different values of guiding parameters and propagation constants, different types of surface waves at the interface between the photorefractive crystal and the linear dielectric medium are formed. When the guiding parameter is greater than the propagation constant, delocalized surface waves can form at the interface. When the guiding parameter is less than the propagation constant, shock and localized surface waves can occur at the interface. The propagation constant affects the shapes of surface waves, and the guiding parameter affects the propagation and the energy distribution of surface wave at the interface. Every model of photorefractive localized surface waves on drift and diffusion mechanism is given.
