North Carolina State University scientists create lightsaber-like laser antenna
Scientists at North Carolina State University demonstrated a new radio antenna that resembles a lightsaber and uses a laser to transmit radio waves on October 9, 2026.
Laser creates tunable plasma beam
The device replaces conventional metal structures with a narrow beam of plasma generated by a laser. This setup allows the antenna to change its length and direction on demand. Researchers say the technology can transmit across a broad range of frequencies.
Potential uses for satellites
The new concept offers promising applications for wireless communications, radar systems, and space exploration missions. Prya Darshni, a Ph.D. student at the university, noted that the antenna looks like a lightsaber while remaining functional.
