Interaction Problem

The interaction of an electron with two electromagnetic waves propagating in an isotropic plasma is studied. It is shown, by numerical calculations, that the electron behaves stochastically, above a given threshold of the wave field amplitudes. The numerical threshold is compared with those given by analytical criteria. The results might be relevant to the laser-plasma interaction problem.

Transverse Electromagnetic

An experiment has been conducted in which a plane transverse electromagnetic wave is incident from free space on a layer of isotropic plasma at small angles (0–12°) of incidence. Strong longitudinal electrostatic fields are observed within the plasma in the regions where the radian frequency of the incident wave equals the plasma frequency when the electric vector of the incident field is in the plane of incidence. Only weak longitudinal electrostatic fields are observed if the incident electric field is perpendicular to the plane of incidence. The observed phenomenon appears consistent with the field growth in a region where the dielectric coefficient of a plasma becomes zero.

Reflected Wave

We investigate radiation of waves at double the frequency from an arbitrary inhomogeneous, isotropic plasma layer, when 8-polarized electromagnetic waves are obliquely incident on it and their lengths are considerably greater than the width of the layer. We calculate the amplitudes of the radiated waves. We show that, in general, the second harmonics are radiated in the direction of propagation of both the reflected and the transmitted wave being at the basic frequency. At small plasma densities, the second harmonics are emitted practically only in the direction of propagation of the reflected wave at the basic frequency. For normal incidence, there is no wave radiation at double the frequency of the incident wave.

Integral Formulae

Many different problems, associated with the propagation of electromagnetic waves in an inhomogeneous isotropic plasma and governed by second-order differential equations, are reformulated so as to be brought within the scope of a common analytical procedure. Refiexion coefficients, energy considerations, approximation procedures, slab refiexion, and other theorems are considered, the investigations of different physical processes all being attributable to one underlying mathematical method involving integrals, whose integrands contain quadratic products of the field variables and their derivatives in two different arrangements.
