    摘要: 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. Parametric generation of other signal waves that are phase matched with the signal wave produced by the input drive signal is also possible under appropriate conditions. The left-handed nonlinear transmission line system generates such output signal frequencies with high efficiency.

    摘要: A tunable frequency transmission line pulse forming network circuit for forming a waveform having a spectral content. The pulse forming network circuit comprises a dielectric material; a ground section; a stepped shaped charged section, with the charged section having a plurality of stages including a first stage; a power supply coupled to the pulse forming network circuit for charging the pulse forming network circuit; a switch coupled to the pulse forming network circuit for periodically discharging the pulse forming network circuit; and an antenna coupled to the pulse forming network circuit for propagating a high-power microwave signal from the pulse forming network circuit into the environment. At least the first stage of pulse forming network circuit has one of a tunable magnetic material and a nonlinear magnetic which facilitates adjusting the waveform and the spectral content of the waveform emitted by the pulse forming network circuit into the surrounding environment.

    摘要: A non-magnetic material frequency selective limiter circuit has first and second resonators and a non-linear coupling component. The first resonator oscillates at a fundamental frequency. The second resonator oscillates at one half of the fundamental frequency. The non-linear coupling component non-linearly and parametrically couples the first resonator and the second resonator. The first resonator, second resonator and the non-linear coupling component are arranged so as to reduce the amplitude of an output signal for an input signal of frequency ω when an input signal amplitude is above a voltage threshold value, by converting part of the input signal to a signal at the frequency ω/2. The first resonator, second resonator and the non-linear coupling component are formed of non-magnetic materials.
