Interaction of microwave and magnetoactive plasma in microwave’s plasmatrons

A method for calculating the interaction of a microwave with a plane layer of magnetoactive low-pressure plasma under conditions of electron cyclotron resonance is presented. In this paper, the plasma layer is situated between a plane dielectric layer and a plane metal screen. The calculation model contains the microwave energy balance, particle balance and electron energy balance. It is demonstrated that the description of the microwave electromagnetic properties of the magnetoactive plasma by means of the conductivity tensor or the resistivity tensor must only be applied to a uniform plasma. For a nonuniform magnetoactive plasma the equation that expresses the microwave properties has been found. The importance of taking into account the viscosity of the plasma is shown. Numerical calculations of the microwave-plasma interaction for a one-dimensional (1D) formulation of the problem are presented.
