Abstract

The localized states in a three-layer structure consisting of two nonlinear crystals with positive nonlinearity, between which a linear plate of finite thickness is clamped, and the layer interfaces are characterized by a nonlinear response are arised. The frequencies of such localized states are obtained that exist only at different values of the intensity of interaction of the layer interfaces with excitations. The conditions for the existence of such states are found and estimates of the characteristic scale of field localization are obtained.
