Antennas
Beyond the invisibility cloak and invisibility devices
Perfect absorber of light
Conclusion
Is it possible?
First of all, lets talk about metamaterial.

~What is it?

A material engineered to have a property that is not found in nature.
A comparison of refraction in a left-handed metamaterial to that in a normal material
So... Harry Potter's cloak of invisibility could exist?
Yes! And there's no magic
It also could help surgeons
