It might be small, but it’s a big feat. A lens has been built that is thinner than the waves of light it focuses. Such lenses, made from light-warping metamaterials, might someday replace the ...

A proposed space telescope would focus light primarily with a patterned sheet of metal rather than a large mirror or lens. The telescope ... it through a certain pattern of holes carved in an ...

Instead of the electrostatic and magnetic fields employed in conventional electron lenses, they utilized a light field electron-lens. Electron microscopy enables researchers to visualize tiny ...
