A US-British team of scientists has successfully tested a cloak of invisibility in the laboratory.
The device mostly hid a small copper cylinder from microwaves in tests at Duke University, North Carolina.
It works by deflecting the microwaves around the object and restoring them on the other side, as if they had passed through empty space.
But making an object vanish before a person's eyes is still the stuff of science fiction - for now.
We've opened the door into the secret garden Prof John Pendry, Imperial College London The cloak consists of 10 fibreglass rings covered with copper elements and is a "metamaterial" - an artificial composite that can be engineered to produce a desired change in the direction of electromagnetic waves.
This is done by tinkering with the physical structure of the material, not by altering its chemistry. In this case, the precise variations in the shape of copper elements patterned on to the ring surfaces determines their properties.
Like light waves, microwaves bounce off objects, making them visible and creating a shadow. But at microwave frequencies the detection has to be made by instruments rather than the naked eye.

Will this thing help me sneak into the chearleaders' locker room or not?
Prepare yourself for an even bigger let-down than those X-Ray glasses you bought.
I bought some of those X-Ray glasses but people could still see me
The Philadelphia Experiment, redux.

"Whaddya mean, they've already got a cloaking device? What did I get dressed up for like this, then? Wait a minute...why is everybody giggling?"

----Old News. The Klingons have had it for quite some time.
Well, and Harry Potter, of course.
This is not new. I have been invisible for a long time. Every time I talk to a hottie, she acts as if I'm not there.
As is often the case, the hype is less than the reality.
Give ME a gov't grant for this. I could do this half-asleep at 5:30 on a Monday morning. Without a A US-British team of scientists to split the grant with!
....Hey, Its more common than you think. :(
...yhea....me too.
Just say something that has 2 or more meanings and try to look innocent. The 'dear in the headlights' look means you buzzed them out, or short circuited them, whatever. Now you have her attention. Use it wisely. Simple, up-front and fun for both of you.
I am with someone and am not a pick-up artist. This is how I got my foot in the door for a long time.
Yes. Composite material can be mixed and formed with graphite and 2 other substances that absorb microwave energy instead of reflecting it. Form also matters- sharp edges reflect microwave energy. The problem is with the tons of weapons that must lock under the wings.
Composite material can also be made to reflect with the use of anodized aluminum powder and 1 or 2 orher metal powders to make cosecant^2 antennas with high gain and narrow beamwidth. Those are used on AC-130 gunships. That's not classified.

----- You have a great gift, my son, use it discretely.
You didn't follow through, though. The next time you went out you should have let her drive and licked her up the cheek to the earlobe to find out where she goes.
I guess I'm the only microwave engineer here. I thought this was going to be a tech discussion about physics. Logic only gets you so far with sweethearts, but it can be fun. Hearts take over when they to come together.
