The inverse skin effect in the Z-pinch and plasma focus

Measurement and interpretation of electrical signals in transient electrical discharges*

“…Notice that, contrary to the situation presented in [28], wires have a diameter large enough as to avoid the effects of polarity on the energy distribution over the wire along the axis length, so electrical circuit equations do not depend on the axial coordinate on the exploding wire metal. In this work modeling of the exploding wire circuit is revisited, clarifying the importance of correct understanding of Faraday's law in the interpretation of obtained current and voltage signals, similar to the ones of previous works like [29][30][31].…”

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

“…In the time interval −13 ≲ ≲ − 8, the field penetrates into the plasma layer, causing its small heating. [5][6][7][8][9][10][11][12]). At time ≲ − 8, plasma is heated less than two times, therefore, penetration of the field takes place in weakly heated plasma.…”

“…The appearance of current on the layer surface in the direction opposite to the acting pulse field at the pulse shutdown is associated with the phenomenon that is called the inverse skin effect (see, for example, refs. [5][6][7][8][9][10][11][12]). Figures 3 and 4a show the presence of the inverse skin effect in the conditions under consideration, when it is necessary to take into account heat transfer.…”

“…In addition, because the heating of electrons occurs in an inhomogeneous field, the particle temperatures are inhomogeneous. [5][6][7][8][9][10][11][12] The change in temperature is accompanied by a change in the conductivity of plasma, which, in turn, qualitatively changes the field distribution.…”

“…Because of these changes, more favourable conditions appear for the inverse skin effect manifestation. [5][6][7][8][9][10][11][12]…”
