Temporal Development and Properties of an Overdense Plasma Produced by High Power Microwaves in a Coaxial Discharge Device
A coaxial plasma-waveguide-system exhibits strong absorption near its dipole resonance. Due to the plasmaguide-mode overdense plasmas can be generated in this device. Ionization dynamics and properties of this discharge are investigated by means of different diagnostic methods; the results are compared with analytical calculations of the dispersion relation in the plasma-waveguide-system. In th...
متن کاملA Study on the Excitation and Resonant Absorption of Coronal Loop Kink Oscillations
We study theoretically the issue of externally driven excitations of standing kink waves and their resonant absorption into torsionally polarized m=1 waves in the coronal loops in pressureless plasmas. We use the ideal MHD equations, for which we develop an invariant imbedding method available in cylindrical geometry. We assume a sinusoidal density profile at the loop boundary where the densi...

Magnetically confined plasma can be heated with high power microwave sources. In spherical torus the electron plasma frequency exeeds the electron cyclotron frequency (EC) and, as a consequence, electromagnetic waves at fundamental and low harmonic EC cannot propagate within the plasma. In contrast, electron Bernstein waves (EBWs) readily propagate in spherical torus plasma and are absorbed str...
متن کاملTransparency of overdense plasma with V shape density profile
In this study, we investigate the transparency of an overdense inhomogeneous plasma slab. This anomalous transmission is achieved when the conditions provided for the incident electromagnetic wave to excite coupled surface waves on the both sides of the slab. These conditions require that the homogeneous overdense plasma, or the metallic film, is placed between two dielectric layers. Here, the ...

In this work, we first produced microwave plasma ball, then changed the ball into a microwave plasma jet by flowing a working gas through a nozzle. The effect of working gas on the thermal characteristics of the plasma ball and atmospheric pressure microwave plasma jet was investigated. We used resonant absorption scheme by a metallic antenna inside a chamber in which led to the ionization of s...
