Spectrum of a resistive plasma slab

UW-CPTC 15-8 Analytical and Numerical Treatment of Resistive Drift Instability in a Plasma Slab

An analytic approach combining the effect of equilibrium diamagnetic flows and the finite ion-sound gyroradius associated with electron-ion decoupling and kinetic Alfvén wave effects is derived to study resistive drift instabilities in a plasma slab. Linear numerical computations using the NIMROD code are performed with cold ions and hot electrons in a plasma slab with a doubly periodic box bou...

Bifurcation of the resistive Alfven wave spectrum

A phase integral (WKBJ) theory of damped modes in a resistive cylindrical plasma column is developed. The theory predicts several phenomena observed previously in numerical studies: (i) the complex frequency w has a point spectrum lying on a locus which is approximately independent of the resistivity, and which intersects the ideal continuum only at its end points (at angles of 45° and 30°); (i...

Interaction of Electromagnetic Waves With a Magnetized Nonuniform Plasma Slab

The absorption, reflection, and transmission of electromagnetic waves by a nonuniform plasma slab immersed in an ambient uniform magnetic field of various strengths are studied in this paper. The effects of the plasma parameters and magnetic field strength on the absorbed, reflected, and transmitted power are discussed. The magnetized nonuniform plasma slab is modeled by a series of magnetized ...
