WebJul 14, 2024 · 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 because it can be used to increase the gain of an antenna, and to quickly reconfigure … WebreflectorCylindrical. reflectorGrid. reflectorParabolic. reflectorSpherical. customDualReflectors.
