  • Plasma controlled antenna
    Patent number: 6621459
    Abstract: An improved plasma controlled millimeter wave (MMW) or microwave (&mgr;W) antenna is provided. A plasma of electrons and holes is photo-injected into a photoconducting wafer. A special distribution of plasma and a MMW/&mgr;W reflecting surface behind the wafer allows the antenna to be generated at low light intensities and a 180° phase shift (modulo 360°) to be applied to selected MMWs/&mgr;Ws.
    Type: Grant
    Filed: January 30, 2002
    Date of Patent: September 16, 2003
    Assignee: Raytheon Company
    Inventors: George W. Webb, Susan G. Angello
  • Metal foams for low radar observability surfaces
    Publication number: 20020190889
    Abstract: The present invention relates to a material of construction which includes a radar-dispersing metal foam, and to a vehicle to which a radar-dispersing metal foam has been applied. The radar-dispersing metal foam is capable of reducing the radar return from an object by a significant amount over a wide range of radar frequencies. The metal foam has a very low reflectivity to incident radar wave radiation.
