It was interesting reading in Nov 2006 Australian Scientist that metamaterials with a negative refraction index promises better than differaction limited view - initially to half the wave length of light, in the near future.
Has anyone read much about this and have any idea how far this idea (at the prototyping stage) is from commercial production?
About 2 years ago I read research in to nano-tube Hartman masks offerred possibilities - but this seemed far more promising!
