Electrodynamic Model of the Gas Discharge Sustained by Azimuthal Surface Waves

Electromagnetic energy rotation along plasma-metal interface in cylindrical waveguides initiated by azimuthal surface waves

“…In studying a capability of XASWs to sustain a gas discharge in cylindrical waveguides, the angular discharge "length" was used in Ref. 24 rather than the linear discharge length commonly used for the case of planar discharge chambers.…”

Influence of the shape of the cross section of a plasma-dielectric interface on the dispersion properties of high-frequency azimuthal surface modes

“…where for each value of the summation index n the terms Δω n are defined in the same way as it is done in expression (10).…”

“…[2][3][4][5][6][7][8][9][10][11]. When doing that, the value of the parameter is chosen to be equal to unit for conve nience of readers.…”

“…Increase in N is not followed by any essential increase in the absolute value of Δω N . An analysis of expression (10) shows that series (11) converges if the small parameters h n decrease with the index of summation n faster than n -3/2 . This require ment is not too restrictive for our study because, when, e.g., the plasma-dielectric interface is square in cross section, the small parameter h n decreases inversely as the square of summation index n:…”

“…An electrodynamic model of a microwave discharge sustained by an ASW was proposed in [10] for the case 1 The article was translated by the authors. of magnetoactive plasma.…”
