Patent number: 10570659Abstract: An electro-optic window is provided, together with a method of manufacturing the window. The window (3) is made of a material substantially transparent to at least one of infra-red, visible and UV radiation and treated to have reduced RF/MICROWAVE transmission characteristics by the provision of a grid (1) set into at least one surface (2) thereof. The grid (1) is formed of a material selected to be either reflective or absorptive to RF/MICROWAVE radiation.Type: GrantFiled: February 2, 2015Date of Patent: February 25, 2020Assignee: BAE Systems plcInventors: Sajad Haq, Hazel Anne Dyke, Michael Dunleavy, Harry John Finn
