This paper reviews the state of knowledge concerning the source of magnetospheric plasma at Earth. Source of plasma, its acceleration and transport throughout the system, its consequences on system dynamics, and its loss are all discussed. Both observational and modeling advances since the last time...
These effects combine for “inverted boat” sheath shapes to deliver more net electrons to the wafer periphery and more net positive ions to the wafer center. When the wafer surface is conducting, surface currents flow to balance the local nonuniformity between the electron and ion currents. If ...
Effects of double-split-ring resonators to plasma local behavior powered by microwavesPlasmas have been studied as optical nonlinear media because of their complex kinetic motions. A plasma sheath is one source of nonlinearity since it includes a rectification factor which induces a nonlinear current....
An electrode with a positive dc bias inserted into a Maxwellian plasma is observed to generate coherent high-frequency oscillations at the sheath-plasma antiresonance frequency (ω≲ωpe). The phenomenon is explained by a negative resistance associated with the finite electron transit time through...

Waves of this frequency can penetrate into plasmas with higher densities only up to the thickness of the skin sheath, which equals a few centimeters, under these conditions. The MW power absorption inside the skin sheath transfers energy into the plasma via waves with a frequency below the cut...
within the plasma, while in the higher regimes ofα, a negative sheath is formed and the negative ion flux can be extracted from the bulk plasma. In... N Oudini,JL Raimbault,P Chabert,... - 《Physics of Plasmas》 被引量: 32发表: 2013年 Resonance behavior of the ion‐sheath capacit...
such as the plasma sheath adjacent to the electrode surface. To enhance the accuracy of arc plasma generation simulation modeling within the LTE assumption, researchers tend to define a local thin layer (sheath layer) near the electrode with constant electrical conductivity as a complement [14]. ...
A new sheath boundary condition has been implemented in VSim, a plasma modeling code which makes use of both PIC/MCC and fluid FDTD representations. It enables physics effects associated with DC and RF sheath formation - local sheath pot... TG Jenkins,SE Kruger,JM Mcgugan,... - APS Meetin...
02+e±O±OThis reaction has a resonance at about 8 eV electron energy, and occurseither in the sheath or in or beyond the orifice. The radial distribution oftheadditionally formed O ions reflects the radial distribution of electronsin the discharge and has nothing to do with the negative ...
