Useful cloaking device is one step closer to reality

Now if you don't find this stuff fascinating I don't know about anything else that could!

In October Duke University discussed a device that enabled them the ability to cloak simple objects from microwave radiation. There are many requirements involving the materials used, etc to pull it off. Of course anything emitting electromagnetic waves (body heat, cellphone, light) would all still be visible. This is where the breakthrough has occured. They have figured out through a new mathematical theory that would support the "hiding" of EM emitting objects.

When you link to the article there are several other links that contain a lot more detail regarding the theory and its potential uses. Take your time and enjoy the fascinating material.
