Potential surface waves at the boundary of a metal with a magnetoactive plasma at finite pressure

Stability of surface waves at magnetized plasma – metal interface

“…it should substitute only those linear solutions of n e and − → V e [8] for the HF SW and its satellites, which give a response with the frequency ω 2 [4,21]. Thus, the nonlinear part of (5) …”

“…The dispersion properties and field spatial distribution of the potential high-frequency (HF) SW at such structure has been investigated earlier in [8]. In this work on the basis of the Poisson and quasi-hydrodynamics equations:…”

“…Hereinafter all quantities corresponding to the HF SW of a finite amplitude we note with the index 1. According to the results of [8], in this frequency region the SWs potential can be written in the following form…”

“…However, many types of plasma -metal waveguide structures operate with a magnetic field oriented perpendicularly to the medium interface [7,8,9,10,11,12]. Such magnetic field configuration are especially typical of plasma processing [13], because the best macroscopic processing uniformity and the best anisotropy are achieved when the static magnetic field lines are perpendicular to the substrate [14].…”

“…But their propagation is possible at a warm plasma. The linear theory of these waves is developed in [8,9], some nonlinear effects caused by the self-interaction are investigated, for example, in [10,11]. Paper [17] is devoted to the parametric excitation of the considered SWs.…”
