Closer to fulfilling the dream of invisibility

"A group of researchers from the Department of Physics at UAB have designed a device, called a dc metamaterial, which makes objects invisible under certain light – very low frequency electromagnetic waves - by making the inside of the magnetic field zero but not altering the exterior field. The device, which up to date has only been studied in theoretical works, thus acts as an invisibility cloak, making the object completely undetectable to these waves."
I'm unsure of exactly where they are at with this - one researcher is quoted as saying "now comes a very important stage: building a prototype in the laboratory and applying this device to improving magnetic field detection technology". It seems they definitely built something, but now have to integrate that metamaterial into a larger machine? Oh well, sounds interesting anyways

The theory of invisibility is not a new concept.During WW2,there were
rumors of a battleship having been cloaked against radar technology
of the time.The Philadelphia Conspiracy,the ship was made invisible.
But,it was reported to have disappeared and reappeared several miles
away from it's original port.
The experts were trying for invisibility but,got teleportation as well.
I don't think this theory was ever proven.
In todays technology,we have "invisibility"by other means.How modern
aircraft are designed to fool radar,by angles they are built and paint used
on their hulls.
It would be interesting to see what the possibilities will be if this does work.

I have to make a correction...
The Philadelphia Experiment and the ship was the U.S.S.Eldridge
