  • Optically transparent article with embedded mesh
    Patent number: 5858496
    Abstract: An optically transparent article is prepared from an optically transparent first piece and an optically transparent second piece. A channel pattern is scribed into a surface of the first piece to a preselected depth. A metallic stripe pattern is deposited into the channel pattern, with the thickness of the metallic stripe pattern being less than the depth of the channel pattern. The second piece is placed over the first piece and sealed thereto at a peripheral boundary such that the second piece does not contact the metallic stripe pattern. A bus connection is optionally made to the metallic stripe, preferably from the periphery of either the first or second piece.

  • Window that transmits light energy and selectively absorbs microwave energy
    Patent number: 5776612
    Abstract: A window includes a first layer of a dielectric first material that transmits radiation in the visible or the infrared, and a second layer positioned adjacent to the first layer. The window is positioned so that the radiation is incident upon the first layer. The second layer is formed of a dielectric or semiconductor second material that transmits radiation in the same wavelength range as the first material. A first electrical conductor lies between the first layer and the second layer. A second electrical conductor lies on at least one of an exterior surface of the first layer remote from the second layer and an interior surface of the second layer remote from the first layer. Where the first and second materials are selected to transmit in the infrared, the first and second electrical conductors are grids. Where the first and second materials are selected to transmit light in the visible, the first and second electrical conductors are continuous layers.
