New Wave: Spin Soliton Could Be a Hit in Cell Phone Communication
NIST researchers believe they can create a stationary wave called a "soliton" in a layer of a multilayered magnetic sandwich.

Researchers at the U.S. National Institute of Standards and Technology (NIST) say they have discovered a new way to generate the high-frequency waves used in modern communication devices, which could lead to the development of a new generation of wireless technology that would be more secure and resistant to interference than current equipment. The researchers have discovered an oscillator that would harness electrons' spin to generate microwaves. The researchers believe that a special type of stationary wave, called a soliton, can be created in a layer of a magnetic sandwich.
"In theory, you could change the frequency of these devices quite rapidly, making the signals very hard for enemies to intercept or jam," says NIST's Thomas Silva. "All we've done at this point is the mathematics, but the equations predict these effects will occur in devices that we think we can realize," Silva says.
