North Carolina State University researchers turn laser beams into a lightsaber-like antenna that sends radio signals without metal and boosts reception by 2.5 times
- PC: NC State news releaseResearchers at North Carolina State University have demonstrated a laser-powered plasma antenna that transmits radio signals without a conventional metal radiating element.
- Resembling a lightsaber, the device uses a laser to ionise air and create a thin plasma filament that transmitted a 30 MHz radio signal during laboratory tests.
- According to the study published in the IEEE Journal, titled ‘Laser-Induced-Plasma-Filament Antenna Transmitting 30 MHz VHF’, the received signal strength increased by approximately 2.5 times when the plasma filament was used as an antenna.
