In this paper experimental results are presented on the radiation patterns and VSWR of the smart plasma antenna. Because of the restrictions of the use of COTS (commercial of the shelf) plasma tubes these designs are not optimized. In addition antenn

We have demonstrated that one or two plasma tubes can be used to focus, spread, and steer antenna beams. We have also shown that we can simulate convex and concave plasma lenses by using cylindrical plasma tubes. Focusing by a plasma is useful becaus

Plasma antennas use partially or fully ionized gas as a conductor instead of metal. Plasma antennas can perform as metal antennas do but with reconfiguration, lower thermal noise at the higher frequencies, and lower side lobes in some experiments. At

A magnetic momentum probe1 is investigated. This diagnostic device appears similar to a Langmuir probe, but interacts with particles by magnetic field rather than (or in addition to) an electric field. The probe is a bare wire loop immersed in the pl
