plasma antenna

Researchers have successfully demonstrated the first-ever plasma beam antenna, according to a science news release. Plasma antennas use ionized gas rather than solid metal conductors to transmit and receive radio signals, a concept long studied for its potential advantages in reconfigurability and stealth applications. The announcement marks a milestone from laboratory theory to a working demonstration, and observers in the physics and telecommunications communities are expected to watch closely for details on its performance and practical uses.
