Abstract: Self organization of the scattered light into dynamic patterns will be discussed for the photosensitive materials (semiconductors and photofractive crystals). Experimental results on rotating hexagonal arrays observed in photosensitive crystal KNbO3 are analyzed, using Maxwell wave equations and diffusion-drift material equations.
