Pretty cool.

Original Article

quote:
Scientists have made the impossible possible, disappearing a cylinder by guiding light around it before putting those photons back on their original path -- essentially bending light around the object. This new approach achieves invisibility where others have failed. With a catch, however: It only works from one direction.
quote:
By doing so, they bent light around their 1 centimeter high, 7.5 centimeter wide cylinder without reflections.

“We built the cloak, and it worked,” said Landy, a graduate student working in the laboratory at Duke’s Pratt School of Engineering. “It split light into two waves which traveled around an object in the center and re-emerged as the single wave minimal loss due to reflections.”

It can only hide objects so small they are not visible to the naked eye, and that success has predominantly been in wavelengths longer than what the eye can, see such as infrared, microwaves and radio.
So, yeah, cool, but not stop the presses cool.

Wait. I don't get it. "It can only hide objects so small they are not visible to the naked eye" but "they bent light around their 1 centimeter high, 7.5 centimeter wide cylinder." a cylinder that size is visible to the naked eye.

Will it stop people from thinking that science is made in headlines?

This begs for video, so you can better see exactly what was accomplished.
