"Perfect Lens" Getting The Fisheye

A very interesting article on the quest for the so-called "perfect" lens. At this point, the leading medium for getting such a device are the metamaterials having negative index of refraction. But as stated in the article, there appears to be another way at getting this via the old Maxwell's fisheye lens.

Now scientists in the UK and Singapore have published experimental evidence that shows perfect lenses don't need negative refraction at all – and that a simpler solution lies in a 150 year-old design pioneered by James Maxwell. If true, the discovery could be a goldmine for the computer-chip industry, allowing electronic circuits to be made far more complex than those of today. However, the work is proving so controversial that the lead scientist has become embroiled in a fiery debate with other experts in the field.

I actually found the controversy surrounding this more fascinating. Isn't that odd? :)

Still, I'm looking forward to seeing how this plays out.
