摘要
We consider the influence of the nonlocal component of the photorefractive crystal response on the cnoidal waves propagation dynamic and analyze the dependence of the self-bending parameter on the degree of the spatial localization of the wave energy. We have shown that for the case of the cn-wave the role of self-bending effects increases (and for the case of the dn-wave decreases) with growth of spatial localization.
