TECHNOLOGY FOCUS
The focus will be on the plasma antenna characteristics and the advantages of plasma antennas over metal antennas. Applications of plasma antennas will be given to MRI/PET, RADAR, GPS, FAR-UVC to kill covid-19 and other viruses, cell towers, 5G and communicating through the plasma sheath during re-entry at hypersonic speeds.
COURSE CONTENT
The course content will consist of dipole plasma antennas, smart plasma antennas, satellite plasma antennas, plasma reflector antennas, reduction of co-site interference, radiation patterns, smart plasma antenna, high power plasma antennas, reflector plasma antennas, pulsing plasma antennas, and how to make a basic plasma antenna.
