Abstract
A window has at least two surfaces oriented relative to each other at an angle greater than zero. A conductive path is disposed across the two surfaces and renders the window reflective or absorptive to a second predetermined bandwidth of energy, which can be radio frequency energy. The window utilizes window geometry, surface treatments, and bonding techniques to maintain electrical continuity across the surface. The window can be constructed from multiple segmented elements, such as sapphire, or from a unitary body. The window is transmissive to a desired wavelength of energy for the sensor while being reflective, refractive, or absorptive to a desired RF bandwidth of energy. The window provides RF signature management coupled with a substantial sensor Field of Regard and allows for full-time use of an embedded sensor.
