Duke University has developed a "Cloaking Device" that is capable of bending light. Bending the light allows 3d objects to virtually disappear. Here is where it gets really interesting. Evidently the device can also bend radio signal, and researchers are suggesting possible uses to bend radio signals around obstructions. This will make antenna more visible to the radio signal, and improve reception. This technology was created using a man made substance called a meta-material. The meta-material is comprised of 10,000 pieces of fiber glass arranged in a parallel pattern on a curcuit board. This technology is currently in its infancy, and already the implications of such a technology seem amazing.
