Radio frequency wave interactions with a plasma sheath: The role of wave and plasma sheath impedances

Studies of Terahertz Wave Propagation in Realistic Reentry Plasma Sheath

Communication ‘blackout’ is a big challenge for modern space engineering. In the recent decade, the terahertz (THz) technology is believed to be an effective solution for the ‘blackout’ problem. Many research works about the transmission of THz waves in plasma slabs have been carried out. According to those works, the radio attenuation of THz waves in plasma slabs strongly depends on thickness ...

Numerical Analysis of Radio-Frequency Sheath-Plasma Interactions in the Ion Cyclotron Range of Frequencies

Electromagnetic plasma waves in the ion cyclotron range of frequencies (ICRF) are routinely used in magnetic fusion experiments to heat plasmas and drive currents. However, many experiments have revealed that wave energy losses in the plasma edge and at the wall are significant, and detected that the acceleration of ions into the walls due to the formation of radio-frequency (RF) sheaths is one...

Study of the Radio-frequency Driven Sheath in the Ion Cyclotron Slow Wave Antennas

The electrostatic Faraday screen(FS) is generally used to suppress the strong electrostatic interaction between the ICRF antenna and edge plasmas near the antenna. It is recognized that FS suppresses the electrostatic field parallel to the magnetic field(E//), and particle and heat fluxes into the antenna current strap effectively. Even with FS, however, impurity generation from FS is a severe ...
