Researchers at Harvard University in Cambridge, Mass., have employed a nanoscale version of skiving — cutting a material into thin layers — to create large-area arrays of patterned metallic structures. By producing frequency-selective surfaces, the nanoskiving technique might yield negative-index-of-refraction and three-dimensional metamaterials, with applications in optical imaging, polarization, filtration and other areas. A bright-field optical image shows an epoxy slab containing U-shaped nanostructures sitting on top of a hole in a copper sheet (A). The inset depicts a scanning...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
