Zone structure of regimes of monochromatic reflected radiation in the parametric doppler effect in plasma

Abstract

The presence of regimes of nonmonochromatic reflected radiation for monochromatic radiation incident on an inhomogeneity moving in the direction of incident radiation is demonstrated for the parametric Doppler effect in plasma. For collisionless plasma, these regimes are related to the transparency of the plasma for incident radiation and its opacity (the total internal reflection) for the reflected radiation. On the plane of parameters of the problem, the velocity of the inhomogeneity and the frequency of the incident radiation, a zone structure (allowed and forbidden zones) of the domains of the existence of the regime of a monochromatic reflected wave is found.
