Evolution of a Dust Void in a Radio-Frequency Plasma Sheath
Physical Review Letters, 2002 The onset and growth of a dust void are investigated in a radio-frequency (rf) sheath of a capacitively coupled argon plasma. A circularly symmetric void emerges and grows with increasing rf power and pressure in the central region of the dust cloud levitating in the sheath.

The Absorption Coefficient of a Plasma at Radio Frequencies [PDF]
Monthly Notices of the Royal Astronomical Society, 1960 The theory of radiation due to free --free transitions by electrons in a plasma has been the subject of much work. Elwert has given an exact theory for binary electron-ion encounters but there has been doubt about the applicability of the formulae when an electron moves in the field of many ions at comparable distances; it is intended to remove that ...

Spatiotemporal evolution of radio wave pump-induced ionospheric phenomena near the fourth electron gyroharmonic [PDF]
, 2007 On 12 November 2001, the European Incoherent Scatter (EISCAT) high-frequency (HF) radio wave transmitter facility, operating in O-mode at 5.423 MHz with 550 MW effective radiated power, produced artificial optical rings which appeared immediately at ...

UHF electromagnetic emission stimulated by HF pumping of the ionosphere [PDF]
Annales Geophysicae, 2002 UHF electromagnetic emission (with a frequency near 600 MHz) from the F-region of the ionosphere pumped by an HF powerful radio wave is revealed. Possible mechanisms of the emission excitation, such as plasma mode con-version, scattering or Earth ...
