I had read this quicky from Nick the other day, and was impressed by the work going on with evanescent waves. This seemed an unusual research topic to me because evanescent waves were always more of a mathematical construct resulting from the equation of motion and not something physical.
Then today in the NYT, they were re-visiting invisiblity. It hadnt occured to me that the negative index of refraction was due to the amplificiation of evanescent waves. A couple of minutes with Jackson* and a look at my EM notes and BOOM! It all fits into place.
The next 10 years in material science is going to be very cool.
