VOLUME 85 | ISSUE 10 | PAGE 594 Spatial Localization of Nonlinear Waves in Layered and Modulated Media I. V. Gerasimchuk, A. S. Kоvalev+ Institute for Theoretical Physics, National Scientific Center «Kharkov Institute of Physics and Technology", 61108 Kharkov, Ukraine +B. Verkin Institute for Low Temperature Physics and Engineering, 61103 Kharkov, Ukraine PACS: 05.45.Yv, 42.65.Tg, 42.82.Et Abstract We describe analytically the nonlinear dynamics of the stationary waves propagating in an anharmonic medium along layered or modulated periodic waveguide system. The exact dynamical equations for discrete systems of coupled anharmonic oscillators, which are typically used for the description of real experiments on the localization of powerful optical fluxes, are analytically derived on the microscopic level and the conditions of their applicability are obtained. The criterion of the appearance of a spatially localized state in such systems is derived.
