  • Radio frequency shielding system
    Patent number: 9038949
    Abstract: An assembly for shielding an aircraft from electromagnetic energy may include a window mounting configured to be conductively coupled to an aperture in a fuselage of an aircraft. The window mounting may include a window pane having an electromagnetically-reflective coating for reflecting electromagnetic energy. The window pane may remain electrically isolated from the fuselage prior to the electromagnetic energy exceeding a frequency of approximately 1 GHz. The window mounting may further include a capacitive gasket capacitively coupling the window pane to the fuselage after the frequency of the electromagnetic energy reflected by the window pane exceeds approximately 1 GHz.
    Type: Grant

  • Radio frequency shielding apparatus system and method
    Patent number: 8800926
    Abstract: A system for shielding an aircraft from electromagnetic energy includes a fuselage, aperture, window mounting, and window plug. The fuselage provides an electrically conductive envelope. The aperture is disposed in the fuselage. The window mounting spans the aperture. The window plug spans the aperture. The window mounting and the window plug are electrically coupled to the fuselage and provide an electrical path spanning the aperture.

  • Method of attenuating electromagnetic energy
    Patent number: 7913385
    Abstract: To attenuate electromagnetic energy, a capacitive bond between a window and a frame is provided by a capacitive coupling. This capacitive coupling includes an elastomeric matrix and a conductive media. The elastomeric matrix provides a seal between the window and the frame. The conductive media is bound to the matrix and conducts electromagnetic energy from the window to the frame.
