Rochester Invisibility Cloak

Not sure if this has been posted here or not. The scientists who invented this cloak have generously included instructions on how to build one for $100.

Also, "This is the first cloaking device that can make an object appear to vanish at multiple angles."

That is super cool! Thanks for sharing.

Also, "This is the first cloaking device that can make an object appear to vanish at multiple angles."

I would argue that this statement is incorrect, because Lubor's Lens as used in his 4D Surprise can do the same. The conditions of the Lubor effect are a bit different, but it also works from multiple angles.

There's a lot of faults with that claim, i can think of several optical method "cloaking devices" that have been around since before any of these scientists were born that have considerably wider viewing angles than this method does.

Also this method is incredibly close to a patent (and several variations thereof) i remember reading in one of my endless research sessions which worked by bending light and creating these cone-shaped invisibility zones.

Someone at Rochester needs to learn how to use google i think?

I think the more precise quote is: "“This is the first device that we know of that can do three-dimensional, continuously multidirectional cloaking."

It's still wrong, there's many many optical systems that work from multiple angles. What they mean is "everyone else is doing this using video camera's and projectors/screens which sort of works but only when viewed in the same plane as the camera, we have created something that's very slightly better than that but still not as good as methods invented 100 years ago"

It's clearly just a word processing error
