Metamaterial optical lens offers efficiency but lacks a focused application

A team of researchers in the Capasso group at Harvard University recently announced the development of a metamaterial lens that focuses light in the visible wavelength with superior light transmission efficiency compared to previous lenses. This lens uses an array of 600 nm tall pillars to focus ...
