Abstract
A window which is transparent to visible light and/or infrared radiation but which absorbs radio frequency energy. The window has a at least two layers of dielectric material separated by a conductor and backed with another conductor. Each layer of the window is selected to be transparent to visible light and/or infrared radiation. The window functions to absorb RF energy in a manner similar to a Jaumann absorber, with the exception that the backing conductor need not be a short circuit. The window is constructed of known window materials, such as glass and plastic, with the conductors being a gold film or indium-tin oxide.
