A new kind of metasurface uses the sun to clear foggy screens

A metasurface is a material engineered to have surface properties that are not found in nature. To find out how the metasurface compares, the team pitted it against an untreated surface and ones coated in superhydrophilic and superhydrophobic materials. The new metasurface is relatively easy to make, opening the way to large-scale manufacture on a wide range of materials such as glass and polymers.
