plasma wave

plasma wave

[′plaz·mə ‚wāv]
(plasma physics)
A disturbance of a plasma involving oscillation of its constituent particles and of an electromagnetic field, which propagates from one point in the plasma to another without net motion of the plasma.

The artist, who has long been fascinated by space, discovered a NASA recording of sounds derived from the plasma wave detector on the Voyager craft as it traveled through waves of electrons in ionized gas.
They cover diagnostics of plasma perturbations by using Doppler radio sounding, diagnostics of plasma wave disturbance by incoherent scatter and Doppler radars, diagnostics of geomagnetic disturbances, rocket burn and launch and radio communication, and ecological problems in near-the-earth space activity.
Speakers on the occasion were - Ed Stone- Voyager project scientist, California Institute of Technology; Don Gurnett - Voyager plasma wave investigation principal investigator, University of Iowa; Suzanne Dodd - Voyager project manager, Jet Propulsion Laboratory; and Gary Zank, physics department chair, University of Alabama in Huntsville.
A report on the analysis of this new data, an effort led by Don Gurnett and the plasma wave science team at the University of Iowa, Iowa City, is published in Thursday's edition of the journal Science.
However, an analysis of data from Voyager's plasma wave science instrument between April 9 and May 22 this year showed the spacecraft was in a region with an electron density of about 0.
The resulting pattern of charges forms a plasma wave, which contains a strong electric field.
TU4C-1 will discuss 140-GHz fundamental mode VCO and a 324-GHz quadruple pushed VCO in 90-nm CMOS, a 410-GHz push-push VCO in 45-nm CMOS, and 180-GHz Schottky diode and 780-GHz plasma wave detectors in 130-nm CMOS, which have been demonstrated.
Menard's research interests have focused primarily on stability properties of ST plasmas, advanced operating scenarios in the ST plasma startup, and plasma wave physics.
Cassini, launched in 1997, carries 12 scientific instruments to image the saturnian system at infrared, ultraviolet and visible wavelengths and with radar, and to sample directly the charged particle, dust, neutral gas and plasma wave environments.
cameras captured the first images of the storm, Cassini's radio and plasma wave instrument detected the storm's electrical activity, revealing it to be a convective thunderstorm.
Additional electrons injected into the plasma could then surf the laser pulse's wake, draining energy from the plasma wave as they steadily picked up speed.
Panel topics during the symposium include space debris elimination, fission fragment rocket engine propelled spacecraft, and the potential for ambient plasma wave propulsion systems.
