Thanks...I had checked there. And in case you wanted to know what it was all about, metamaterials are basically a new kind of material that interact
with light and other electromagnetic radiation in interesting ways - they've been used recently for two pretty major breakthroughs:
1) to construct a "superlens" which beats the diffraction limit. This basically means it's a lens that allows you to see things that are smaller
than the wavelength of light. That's pretty damn small.
2) to create a cloaking device, which curves radiation around an object and then allow the radiation to emerge on the other side as if the object
wasn't there. True invisibility is getting closer. Of course it'll go straight to the military first, but who knows? One day we could have ugly
factories cloaked so that they aren't such eyesores on the landscape.
Anyway, I still would appreciate any explanation anyone can give as to how these materials actually pull off the feats they do. Have searched through
google and found plenty, although unfortunately my scientific knowledge is hardly of undergrad standard, so much of it is lost on me - could anyone
explain in practical layman's terms?
