Researchers have demonstrated a technique that uses a laser to produce a plasma beam antenna capable of transmitting radio waves.

“The plasma beam antenna looks like a lightsaber and is tunable, meaning we should be able to transmit across a broad range of frequencies,” says Prya Darshni, corresponding author of a journal article on the work and a Ph.D. student at North Carolina State University.
