The process of four-wave mixing is of a great importance in guiding systems, since some leaky modes can appear through the possible emission of fast combinative waves. There is an example in papers [1, 2], where the mechanism of radiative losses of electromagnetic energy at a nonlinear interaction of forward and backward surface waves in third order nonlinear plasma films was theoretically investigated. One should note that this effect also takes place at an interaction of volume modes in nonlinear waveguides. It is interesting to seek a similar effect in strongly nonlinear systems, such as spatial solitons, for example. As it is shown in given paper, emission of combinative wave leads to dramatic changes in solitons dynamics, when the usual repulsion or attraction is completely equilibrated by reaction of radiation.
