Bend breakthrough sends light around a corner

13 posts in this topic

Australian National University scientists have successfully bent light beams around an object on a two dimensional metal surface, opening the door to faster and cheaper computer chips working with light.

The international team, including three members from the Research School of Physics and Engineering at ANU, have successfully demonstrated that a tiny beam of light on a flat surface can be bent around an obstacle, and course-correct itself on the other side of that obstacle.It’s the world’s first two-dimensional demonstration of so-called ‘Airy beams’.

oh I don't know! doesn't light bend naturally around objects anyway?

Technically, a beam of light goes straight ahead.... quantum physics are a different animal, however. My brain hurts.

Mmm and this is a little different from refraction ;)

Nope, not without huge gravitational assistance from nearby galaxies it doesn't.

Refraction is another ball park ;)

the cloaking device is close at hand

they already have cloaking... military tech is always years in advance of what's shown to the public.

That isn't cloaking, just that the camera is blending all moving objects/has a low framerate and the guys uniform is similar color to the background of the parts where he looks cloaked. Just look at the guys in the background, and the guys that run from left to right in another part. They have a similar distorting look with movement, but they're uniforms are darker.

Are you thinking objectively or just repeating what others said in the youtube comments? If that were the case why is he the ONLY soldier that appears that way(not to mention he comes from a totally random direction all alone)? If it were distortion it would affect everyone's uniform that follows the same path since there are no variant desert camos that would make distortion affect one person and not the rest and the cameras position didn't change. Secondly, as the other soldiers traverse the same path, the shadow of separation between them and the wall/background is very obvious. The cloaked soldier has none of that.

I notice they didn't say how they are creating the wave. These guys will be rich soon.

Getting a little tired of waiting on that lightsaber, lets get with the program here scientists. <_<
