Abstract
Modified low emissivity (low-E) coated glass, so that windows using the processed glass allow uninterrupted use of RF devices within commercial or residential buildings. Glass processed in the manner described herein will not significantly diminish the energy conserving properties of the low-E coated glass. This method and apparatus disrupts the conductivity of the coating in small regions. In an embodiment, the method and apparatus ablates the low-E coating along narrow contiguous paths, such that electrical conductivity can no longer occur across the paths. The paths may take the form of intersecting curves and/or lines, so that the remaining coating consists of electrically isolated areas. The method and apparatus are applicable both to treating glass panels at the factory as well as treating windows in-situ after installation.
