Effect of heat transfer on the penetration of an electromagnetic pulse into a plasma layer and the inverse skin effect

Abstract

Penetration of a heating pulse into a plasma layer was studied using the system of coupled nonlinear equations for electric field, electron, and ion temperatures. Numerical calculations of field structure and temperature evolution are performed both in the absence and in the presence of heat transfer. It is established that heat transfer leads to a more rapid penetration of the field near the illuminated surface of the layer and impairs penetration in regions of the layer far from this surface. We found that heat transfer promotes the creation of more favourable conditions for manifestation of the inverse skin effect.

Penetration of a Heating Electromagnetic Pulse into Plasma in Magnetic Field

“…( 15) determines the energy density that is transferred to the ions per unit time, which is accompanied by their heating. Herewith, the evolution of the ion temperature is described by the equation (16) In Eq. ( 16) for the density of the -component of the ion heat flux, we use the expression obtained in the…”

“…Herewith, a time limit of electromagnetic pulse effect was taken into account [14,15]. Effect of a strong heating electromagnetic pulse on laminar plasma was studied in [16]. In [16], a numerical solution of the coupled system of equations for electric field strength and temperatures of electrons and ions was given, which allowed us to describe the effect of electron heat transfer on field penetration.…”

“…Effect of a strong heating electromagnetic pulse on laminar plasma was studied in [16]. In [16], a numerical solution of the coupled system of equations for electric field strength and temperatures of electrons and ions was given, which allowed us to describe the effect of electron heat transfer on field penetration. The present communication is devoted to further study of penetration of a heating electromagnetic pulse into laminar plasma under conditions similar to those considered in [16], but taking into account effect of constant magnetic field on heat transfer by electrons and ions.…”
