PLASMA DENSITY REDUCTION USING ELECTROMAGNETIC E×B FIELD DURING REENTRY FLIGHT

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / As a vehicle reenters or flies at hypersonic speed through the atmosphere, the surrounding air is
shock heated and becomes weakly ionized. The plasma layer thus formed causes a
communication problem known as ‘radio blackout’. At sufficiently dense plasma conditions, the
plasma layer either reflects or attenuates radio wave communications to and from the vehicle. In
this paper, we propose an electromagnetic field configuration as a method to allow
communication through the plasma layer. Theoretical models show that this may address the
blackout problem under a range of conditions. Preliminary experimental results are also
presented.
