Power-flux-dependent polarization of nonlinear surface waves.

The complete set of Maxwell's equations coupled by means of intrinsic nonlinearities in Kerr-type media has been analyzed and the integrated power flux has been found as a function of refractive index for hybrid TE-TM nonlinear surface waves. We demonstrate that for a fixed refractive index the electric-field vector of the nonlinear surface waves rotates with an adiabatic increase of the power flux from pure TE polarization at the threshold to pure TM polarization at the cutoff, passing through all possible hybrid polarization states for intermediate power fluxes.

Enhanced Raman scattering in a flowing plasma.

The growth rate for the Raman scattering instability has been found for the case when the plasma flow has a component perpendicular to the wave vector of the pump. Such a configuration allows the pump and the scattered waves to be linearly converted into corresponding longitudinal waves. The linear conversion has a resonant character that results in an enhancement of the growth rate of the parametric process.

Hybrid TE-TM nonlinear guided waves.

The first integral of the complete set of Maxwell's equations coupled through intrinsic nonlinearities in Kerr-type media has been found. The application of this result to wave propagation along a nonlinear optical waveguide leads to a general dispersion relation for nonlinear surface and guided waves of arbitrary polarization, i.e., hybrid TE-TM waves.

Surface wave induced high transparency of an overdense warm plasma layer.

We have found conditions in which a structure consisting of an overdense warm plasma layer spaced between two underdense warm plasma layers becomes transparent to a p-polarized obliquely incident electromagnetic wave. The energy of the incident wave is transferred across the overdense region by a pair of coupled surface waves.
