THE ANOMALOUS ABSORPTION OF ELECTROMAGNETIC ENERGY IN PLASMA,
Abstract
Consideration is given to the effect of anomalous absorption of the energy of an electromagnetic wave which is perpendicularly incident to the surface z = 0 of a semi-infinite plasma. An expression is given for the amplitude of the wave inside the plasma in terms of the amplitude of the incident wave. The dispersion equation for potential perturbations of the stationary state is analyzed for the case where electrons are in motion with a given vector with respect to ions. The consideration is limited to the case of cold ions and motion of the ions in the wave field is disregarded. The hydrodynamic oscillations described by this analytical function are discussed. Expressions are derived for critical conditions and instability. The limits of applicability for the proposed model of energy absorption are analyzed. (Author)
