“…Материалы, обладающие нелинейной восприимчивостью, есть среди сред с диэлектрической проницаемостью, близкой к нулю [19,30,31]. Нелинейную восприимчивость керровского типа могут иметь металлы [32][33][34][35][36]. На границе раздела диэлектрика с нелинейной восприимчивостью третьего порядка и ТИ может существовать поверхностная волна, являющаяся суперпозицией поперечной электрической (ТЕ) и поперечной магнитной (ТМ) волн, если переносимая ею мощность превышает определенное пороговое значение [27].…”

The surface waves that propagate along the interface of a dielectric with nonlinear susceptibility of the third order and topological insulator have been considered. The optical nonlinearity of the dielectric ensures the existence of a surface wave. The density of the spin angular momentum of a surface wave has been determined for dielectrics with positive or negative linear permittivity. It has been shown that the spin angular momentum vector has a projection on the normal to the interface, which is different from the usual surface polaritons or plasmon polaritons. The discrete nature of the topological number manifests itself in the discreteness of the values of the normal and tangential components of the spin angular momentum density. The increase in the intensity of the electric field of the wave at the interface of the media changes the value of the spin angular momentum and can lead to its disappearance.

The main results of works on study of influence of nonlinearity on propagation of radio waves through metals placed in a constant magnetic field are described. The trapping of carriers by the magnetic field of a wave with a large amplitude leads to suppression of collisionless absorption and to a possibility of propagation in metals of waves of various types. In copper, the propagation of helicons becomes possible in the geometry when on the Fermi surface there are open orbits preventing from wave propagation. In zinc, in which the cyclotron absorption by holes exists for any wave lengths in the linear regime, the decrease of this absorption results in a possibility of propagation of an electron doppleron. In noble metals and metals of the Third Group, where any waves are absent in the linear regime, the propagation of nonlinear waves of the new type, which do not have counterparts in the linear regime, becomes possible in the range of weak fields. Multiple reflections of nonlinear waves from internal surfaces of a metallic plate lead to the formation of standing waves in a sample. In this case resonance maxima appear in a dependence of the surface resistance of the sample on a constant magnetic field. In the maxima the transparency coefficient of a metal with respect to radio emission can increase by one-two orders of magnitude.
