Welcome to the U.S. Army Research Laboratory (757 words) |
 | Researchers funded by the Army Research Laboratory’s Army Research Office have demonstrated what was once thought impossible: the speed of light can be slowed, halted entirely, or in some cases, even reversed. |
| However, researchers have long recognized that it is sometimes important to slow this speed, and consequently, recent breakthroughs in “slow light” research have been deemed exciting. |
| Researchers at the University of North Carolina, Charlotte, demonstrated the ability to reduce by a factor of two light speed in the microwave region using alternating layers of anisotropic materials, an exciting finding because it is makes possible the ability to scale down the microwave wavelength of centimeters to submicron sizes. |
