Very‐high‐frequency–ultrahigh‐frequency shape demagnetizing effects

Autor: S. T. Ratliff

Publikováno v: Journal of Applied Physics. 67:3867-3871

Previous studies by various researchers show the influence of material shape ofn apparent permeability at zero frequency and predict that this will still be valid at higher frequencies. In this paper we demonstrate the influence of shape demagnetizin

Computer simulations of magnetosonic waves, velocity-shell instabilities, and upper-hybrid heating show evidence of a general damping mechanism for large-amplitude electrostatic waves propagating perpendicular to a magnetic field: Particles trapped b

Instability of Streaming Electrons Confined by Surface Magnetic Fields

Autor: J. N. Leboeuf, John M. Dawson, S. T. Ratliff

Publikováno v: Physical Review Letters. 50:1990-1993

It is shown by theory and computer simulations that streaming electrons confined by a surface picket-fence magnetic field (periodic array of magnetic cusps) are subject to a two-stream instability between the electrons trapped by the surface cusp fie

Ion skin depth scaling and cusp distortion in picket fence geometry

Autor: J. M. Dawson, S. T. Ratliff

Publikováno v: Physics of Fluids. 27:1743

Computer simulations show that when a low‐frequency (ω=0 in the simulations) external electric field is applied to a cusp‐confined plasma, some of the electrons are trapped by the cusp fields, and the ions do a significant amount of shielding of
