  • Coherent near-field array
    Patent number: 8134510
    Abstract: A coherent near-field array. The array consists of a number of high-gain elements, each of which directs its beam at the desired target area (either mechanically or electronically). Each element is coherently fed, so that the phase relationships between different feeds are constant or slowly varying. The elements in the array may be spaced many wavelengths apart. The array relies on interference to generate a number of power density peaks within the target area.
    Type: Grant

    Date of Patent: March 13, 2012
    Assignee: Raytheon Company

  • Chalcogenide glass nanostructures
    Patent number: 7211296
    Abstract: Chalcogenide nanowires and other micro-and nano scale structures are grown on a preselected portion of on a substrate. They are amorphous and of uniform composition and can be grown by a sublimation-condensation process onto the surface of an amorphous substrate. Among other uses, these structures can be used as coatings on optical fibers, as coatings on implants, as wispering galleries, in electrochemical devices, and in nanolasers.
