Abstract
A high-transparency, low-emissivity window film or coating is designed to maximize so-called greenhouse heating. This effect is achieved through the use of conductive grids and/or gratings whose width and spacing has been selected such that the grid appears as a uniform conductive film to long-wavelength infrared (blackbody) radiation. The conductive grid film reflects the blackbody radiation strongly, and such that the grid appears highly transparent to visible and near-infrared light, and therefore transmits it.
