Surface waves parametric excitation in planar plasma filled waveguides

Summary form only given. The report is devoted to the investigation of the parametric excitation of the surface waves on the second harmonic of electron cyclotron frequency (SW) in an uniform planar plasma layer bounded by two thick dielectric slabs. The external steady magnetic field B/spl I.oarr//sub 0/ is applied parallel with respect to the plasma-dielectric interface. The studied SW are extraordinary polarized modes and propagate across B/spl I.oarr//sub 0/. The problem is solved in the kinetic approach under the condition of weak plasma spatial dispersion. The amplitude value of the electric pump wave is assumed to be a small one. We consider the case of a dense plasma (plasma frequency is much greater than a cyclotron one). The effect of the pump wave and waveguide parameters on the increment value is studied.
