ALBUQUERQUE, N.M. — Ever since the first human placed a bare hand on an uninsulated electric line, people have refrained from personally testing energetic materials. Even meters made of metal can melt at high voltages. Now, using a crystal smaller than a dime and a laser smaller than a shoebox, a Sandia National Laboratories team […]

Guiding Light: Sandia creates 3-D metasurfaces with optical possibilities
March 9, 2017 – 5:00 am
ALBUQUERQUE, N.M. — Metamaterials don’t exist in nature, but their ability to make ultra-thin lenses and ultra-efficient cell phone antennas, bend light to keep satellites cooler and let photovoltaics absorb more energy mean they offer a world of possibilities. Formed by nanostructures that act as “atoms,” arranged on a substrate to alter light’s path in […]
