Simple ‘superlens’ sharpens focusing power

University of Michigan researchers have created a simple-to-make planar “superlens” that can focus 10 times more sharply than a conventional lens.
It could shrink the size of features on computer chips by focusing light into smaller spots during photolithography to etch smaller features onto computer chips, and facilate wireless transmission of power.
