  • High power pulse generator
    Patent number: 8744004
    Abstract: A systems, pulse generators, apparatus and methods for generating a high power signal are presented. A pulse generator includes a generator and a modulator unit. The generator generates a bipolar signal. The modulator unit modulates the bipolar signal with oscillating signals to generate a modulated bipolar signal with oscillating portions. The frequency spectrum of the modulated bipolar signal contains very little to no direct current (DC) component.

  • Left-handed nonlinear transmission line media
    Publication number: 20050270091
    Abstract: A left-handed nonlinear transmission line system has multiple nonlinear capacitors connected in series between input and output terminals and multiple inductances connected in parallel between the nonlinear capacitors and a return conductor extending between the input and output terminals. The nonlinear capacitors have a capacitance characteristic that changes with the voltage applied across the capacitors, such as a capacitance that decreases with increasing voltage. A radio frequency signal source is coupled to the input terminals and provides power at a selected drive frequency. Depending on the frequency of the drive signal with respect to the Bragg cutoff frequency of the nonlinear transmission line, the output signal may include a strong signal component at the third harmonic of the input drive signal frequency, components at higher harmonics, or components at fractional frequencies of the input drive signal frequency.
