Dispersion theory of surface waves on an inhomogeneous plasma in a strong high-frequency field

The spectrum of the characteristic surface oscillations and stability of a plasma in a strong high-frequency (hf) electric field are studied. It is shown that inhomogeneity of the plasma leads to spatial dispersion and to specific damping of stable oscillations of a plasma in an external hf field, the frequency of which greatly exceeds the plasma frequency. A systematic theory of parametric resonance at the frequency of the electronic surface oscillations is developed taking account of the inhomogeneity of the plasma.
