Spatio-temporal plasma heating mechanisms in a radio frequency electrothermal microthruster

Spatiotemporal study of gas heating mechanisms in a radio-frequency electrothermal plasma micro-thruster

A spatiotemporal study of neutral gas temperature during the first 100 s of operation for a radio-frequency electrothermal plasma micro-thruster operating on nitrogen at 60 W and 1.5 Torr is performed to identify the heating mechanisms involved. Neutral gas temperature is estimated from rovibrational band fitting of the nitrogen second positive system. A set of baffles are used to restrict the ...

Spatio-temporal diversity in ultra-wideband radio

One of the potential benefits of the UWB radio is its multipath resolution. The implications are multipath components which might not be resolved as distinct arrivals in more narrowband systems, may be separately identified in UWB systems. This paper explores some of the propagation characteristics associated with UWB signals, based on measured data.
