Abstract: Provided are novel energy-efficient signal-transparent window assemblies and methods of fabricating thereof. These window assemblies are specifically configured to allow selective penetration of millimeter waves, representing current and future wireless signal spectrum. This signal penetration is provided while IR blocking properties are retained. Furthermore, the windows assemblies remain substantially transparent within the visible spectrum with no specific features detectable to the naked eye. This unique performance is achieved by patterning conductive layers such that the conductive layer edges remain protected during most fabrication steps and the fabrication. As such, the conductive layers are encapsulated and being separated from the environment while retaining separation between individual disjoined structures of these layers. For example, a barrier layer and/or a dielectric layer may extend over the conductive layer edge.

Abstract: Described are energy-efficient signal-transparent window assemblies and methods of fabricating thereof. These assemblies remain IR-blocking properties while allowing signal penetration and remain substantially transparent within the visible spectrum with no features detectable to the naked eye. This performance is achieved by isolating conductive layers into discrete cells via gap patterning. The second coating stack's line widths are at least 0.4 micrometer greater than the gaps among the primary stacks. The thickness of the primary stack increases from zero to full thickness near the gap, with a sidewall transition length exceeding 0.2 micrometers. The fabrication process involves lithography for patterning, PVD coating, and post-clean and high-temperature treatments. In some examples, a transparent organic thin layer is provided between the second coating stack and the primary stack or the substrate.
