THE REGULAR AND CHAOTIC DYNAMICS AT WEAK-NONLINEAR INTERACTION OF WAVES

It is shown that different regimes at weak-nonlinear interaction of waves are possible: regular regimes with the growth of degree of coherence of some waves which take part in interaction and also chaotic regimes. It is shown that in some cases the increasing number of waves which take part in interaction leads to significant simplification of dynamics of interacting waves and not to complication. Possible electrodynamics structures in which the regimes with dynamical chaos can realize are discussed in this paper. In particular the properties of plasma waveguides filled with rare plasma are investigated. It is shown that in such waveguides the regimes with chaotic dynamics may be realized.
