Abstract: The filamentation dynamics of a nitrogen pulsed microwave discharge generated at the antinode of a standing electromagnetic wave at a pressure of 100 torr has been numerically simulated. The results of the dynamics of the main plasma parameters, such as the concentration of charged and excited species, gas temperature, and vibrational temperature of nitrogen, are presented.

Abstract: The paper is dedicated to the numerical study of the dependence of plasma antenna resonance wavelengths on pressure. The study was carried out by simulating a RF capacitively coupled plasma with the Comsol Multiphysics software in one- dimensional formulation. Based on the calculated electric current in the plasma, the directional pattern and axial distribution of the electromagnetic field were found by solving Maxwell's equations in a 2D formulation. The results showed that one of the advantages of plasma antennas is the transmission of waves at significantly longer wavelengths compared to metal antennas of similar geometry.
