Opis:: The propagation of relativistic electron-cyclotron waves in a hot plasma channel with a parabolic density profile is discussed. Analytical calculations are performed to find the governing equation for the evolution of the pulse spot size including the effects of relativistic self-focusing, ponderomotive self-channeling and preformed channel focusing. Also, by analyzing the equation of the pulse spot size, the existence of some solitary wave solutions is predicted numerically.

Opis:: We present optimization of energy transfer in the waveguide-supplied metal-cylinder-based microwave plasma module with an inner cylindrical quartz tube. The construction of microwave plasma module is based on a WR 340 waveguide standard. Presented microwave plasma module operates at atmospheric pressure and frequency of 2.45 GHz. There is a reduced height section waveguide in microwave plasma module which provides local increase of the electric field in the plasma region. Microwave plasma module is terminated with a movable plunger which plays the role of the tuning element. Tuning characteristics of microwave plasma module are defined as the dependence of the $P_{R}$/$P_{I}$ on the position $l_{s}$ of the movable plunger, where $P_{R}$ and $P_{I}$ are the microwave power reflected and power incident, respectively. The powers $P_{R}$ and $P_{I}$ are measured in the input plane of microwave plasma module. The purpose of the presented optimization is to achieve $P_{R}$ lower than 5% of $P_{I}$ in widest range of position of movable plunger $l_{s}$. We used Comsol Multiphysics software to make numerical analysis which allows to optimize the parameters of microwave plasma module. Results of numerical analysis show that $P_{R}$/$P_{I}$ is lower than 0.05 in a wide range of movable plunger position $l_{s}$.
