Effects of Non-Maxwellian Electron Distribution Function to the Propagation Coefficients of Electromagnetic Waves in Plasma

The values of the propagation constants of electromagnetic (EM) waves through the plasma using as the example of a homogeneous plasma layer for different electron distribution functions (EDFs) are the subject of this paper. The Maxwellian, Druyvesteyn, Pipe-line, and Bi-Maxwellian distribution functions were considered in this paper. Using values of the complex dielectric permittivity obtained from using different EDFs, the results for corresponding reflection, transmission, and absorption coefficients can be significantly different. The EDFs sometimes can have a considerable effect on the dielectric properties of plasma. Hence, comparing the results obtained, it is helpful to analyze the interaction between EM waves and plasma and provide a theoretical basis for the experiments.
