Evolution of a Dust Void in a Radio-Frequency Plasma Sheath [PDF]
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.

On the role of secondary electron emission in capacitively coupled radio‐frequency plasma sheath: A theoretical ground [PDF]
Plasma Processes and Polymers, 2019 We propose a theoretical ground for emissive capacitively coupled radio-frequency plasma sheath under low pressure. The rf sheath is assumed to be collisionless, and oscillates with external source.

Resonance Cones in the Field Pattern of a Short Radio Frequency Probe in a Warm Anisotropic Plasma [PDF]
, 1970 An experimental investigation of the angular field pattern of a small radio frequency probe in a plasma in a magnetic field is described. The field is observed to become very large along a resonance cone whose axis is parallel to the static magnetic ...
