Researchers create a hyperbolic metasurface on which light propagates with completely reshaped wafefronts
Light waves usually disperse in cirular or convex wavefronts form, like ripples on water surface created by a stone. But now researchers have found that it is possible to alter light's wavefronts and to give them a completely new shape.
To observe the waves as they propagate along the metasurface, researcher created a surface based on boron nitride. The material was selected because it has the ability to manipulate infrared light on extremely small length scales and it requires an extremely precise structuring on the nanometer scale to fabricate altered wavefronts. Then, researchers placed an infrared gold nanorod onto the metasurface, which acted like a stone dropped into water.
By using state-of the-art infrared nanoimaging technique, researchers were able to capture the waves.

Researchers suggest that the same method can also be applied to other materials, which could pave the way for better sensing and signal processing optical devices.

Does that mean we’ll have to walk on our hands now to see things correctly, or do we just get used to it?
NOT my fault.
This could make the custom car painting people go bananas!..............
Is this like the back side of waterfalls?

Just think of what they could do with a convex mirror and a prism.....
I will have my Harry Potter cloak

Maybe you will
Sounds like what you’re looking at in Larry Niven’s version of hyperspace. According to him, it drives you crazy.
“Does that mean we’ll have to walk on our hands now to see things correctly, or do we just get used to it?”
The didn’t actually turn light upside down.
I’ll await Dr. Sheldon Cooper’s comments.
He’s busy trying to grow his own Leonard Nimoy.
On The Waferfront was a good movie. A photon says "I coulda been a contender. I coulda been somebody."
Wondering how the ‘photos’ were generated, I found this:
Illustrations, NOT PHOTOS.
Darks doesn't look at it. He lives it.
It's what comes of working in a GPS ley line nexus.
Like normal light, does the light in it’s altered wave forms have an infinite distance it can possibly travel (if not otherwise disrupted)? Or are the light-wave-forms ONLY “observable” at very small distances? Are they wave forms less disrupted by planetary and solar atmospehere’s than “normal” light? More questions about practical applications?
That was THE BEST episode.
