A scale and an invisibility cloak?

Weird combo.

I have an invisibility cloak. It's called a wall. It is sometimes foiled by windows.

FTFA:

The mirror cloak is not actually a new design and has been used for years by magicians, a point the Howells readily acknowledge.

So, just a naked old guy that we're supposed to pretend not to see...or smell, especially when he has taco bell for lunch?

That's...wait a tic.  Scientists, until now, have never considered how invisibility magic tricks work?  I can't decide whether to be impressed that something so simple could actually provide cloaking tech for satellites, or disappointed that no one thought of this until now.

This wouldn't conceal satellites from infrared sensors though, right?

I think that's what the fog machine is for. Or Synergy.

Still needing a holocaust cloak...

My scales are already invisible.

Except when the weather's been really dry for a while.

Yo momma's so fat, her scale is invisible to her.

Why don't they just paint it pink and erect an SEP field?

Why that they haven't?  It's not as if any government would volunteer that they were using invisible satellites, and I could imagine we would have a hard time spotting them.  The concept of invisibility itself should elude to the fact that just because you can't detect something doesn't necessarily mean it isn't there.

If the magician trick only makes objects invisible in the optic frequency range, it's useless for military applications.  Sensors using other frequencies (infrared, radar, etc) would still pick them up.

The impression I got from the article was that the drawback was that it only worked at certain angles. That said, I'm no matetials scientist.

Meh,

Tom Cruise used this in Mi4 didn't he? Old Tech.

Now this is impressive........

Can't wait till they make the harnesses to strap these to sharks heads!

Although invisible satellites are probably pretty elusive.

I know a certain G.O.B. who could assist in such an operation...

Man, it wouldn't post the gif.  Much less dramatic a post.

The mirror cloak is not actually a new design and has been used for years by magicians, a point the Howells readily acknowledge. "The point we wish to emphasize is not the novelty but the ease of scaling to nearly arbitrary size," they say.

So they've invented the idea of making a large mirror instead of a medium size mirror. I bet they get a patent and make me remodel my bathroom.

So is the normal way to look for a satelite some sort of visual search. Do the Chinese just have a bunch of people laying on their back watching the night sky out in the country side somewhere?

Infrared is just another wavelength of em radiation, like visible light is. Mirrors can be made specifically to reflect IR as well as visible. Even a normal household mirror reflects a lot of IR, which is why you can feel the heat of reflected sunlight from a mirror or window, and why you can set things on fire with a concave mirror.

Exactly what I was thinking. This is like scientists researching optical data storage building a big reel to reel tape drive and saying "we just want to illustrate that more tape means more data".

What's their next experiment going to be? Turning off the lights in the room so you can't see the chair? "Look! Without EM radiation of any kind, EVERYTHING can be rendered invisible!"

Would be funny if one day you're minding your own business when suddenly, you see a floating dick in front of you. Flashers of the future lol!
