  • Generation of high-frequency, high-power electrical signals from low-frequency, low-power lattice network structures as sources
    Patent number: 8692629
    Abstract: An apparatus and method for outputting high-frequency, high-power signals from low-frequency, low-power input is disclosed. The apparatus and method may provide a two-dimensional nonlinear lattice having a plurality of inductors and voltage-dependent capacitors intersecting at a plurality of nodes. Two or more adjacent boundaries of the nonlinear lattice may be provided with input signals which constructively interfere to output a signal of substantially higher amplitude and higher frequency than those of the input signals.
    Type: Grant
    Filed: May 19, 2009
    Date of Patent: April 8, 2014
    Assignee: Cornell University
    Inventors: Ehsan Afshari, Harish Bhat

  • 2D transmission line-based apparatus and method
    Patent number: 7671702
    Abstract: A power combiner comprising an LC lattice structure is shown, together with a method for generating a planar wave front. The LC structure can comprise constant or voltage dependent capacitors. Either the delay or the characteristic impedance of the two-dimensional transmission line formed by the LC lattice structure are kept constant. A planar wave propagating along one direction of the transmission line gradually experiences higher impedances at the edges, creating a lower resistance path for the current in the middle. This funnels more power to the center as the wave propagates.
