“…Due to the hysteresis in the ferrite, after this initial shock, the transmission line is linear and signals riding on the pump pulse behind the shock propagate on a linear circuit [2]- [6]. Coaxial ferrite filled NLTLs using an external axial magnetic bias field have been called gyromagnetic oscillators if they derive the RF generation from damped gyromagnetic precession of ferrite domains subject to a rapid change in the direction of the external field [7]- [10]. The NLTLs which derive the operating frequency from the phase matching of a shock front with a slow RF wave have been labeled as synchronous wave NLTLs [3]- [6].…”

A spatially dispersive nonlinear transmission line (NLTL) using axially biased ferrite as the nonlinear medium has been developed. The NLTL is frequency tunable from 0.95 to 1.45 GHz with adjustment of the axial biasing field. A circuit model describing the dispersion of the line has been developed and compared with experimental measurements and time and frequency domain simulations. Instantaneous peak power levels exceeding 100 MW and average power levels of 10s of MW with durations from 4 to 17 ns have been observed.Index Terms-High power microwave generation, nonlinear circuits, pulse power systems.

Great interest has been devoted to the study of nonlinear transmission lines (NLTLs) for radio-frequency generation. The two better known configurations of NLTLs are a dispersive line consisting of sections with nonlinear components and a continuous nondispersive line called gyromagnetic line. The goal of this paper is to study the gyromagnetic line through the effects of changing the NLTL parameters. This is done based on an analytical model supported by SPICE circuit simulations and validation of results with numerical analysis, focusing on the pulse rise time compression. Different models are studied by comparing simulations with corresponding results found in the literature. Such a technique could be used for the design of NLTL for space applications and mobile defense platforms of compact size.

“…Introduction: Nanosecond and sub-nanosecond pulses having high peak power combined with high-speed bursts can be used in applications such as: through-wall imaging [1]; underground detection [2], biological research [3]; and in high energy density physics experiments. Although technologies such as spark-gaps [4] and pulse compression by non-linear transmission lines (NLTLs) [5] can reach tens to hundreds of kilo-volts in the sub-nanosecond regime, the pulse repetition frequency (PRF) of these technologies is limited to the sub-kilohertz range. In this Letter, a pulse compression technique featuring a compact all-solid-state circuit with air-coils is presented, where a PRF of 100-kHz in burst mode is demonstrated.…”

Drift-step-recovery diodes (DSRDs) are used as ∼ 1 ns high-voltage opening switches by pumping them slowly in the forward direction and then pulsing them quickly in the reverse direction. The fast opening occurs when the reverse current discharges the carriers that were stored in the DSRD junction during the forward cycle. Typical forward and reverse timescales are tens and a few nanoseconds, respectively. Although a state-of-the-art metal-oxide semiconductor field effect transistor may pulse the DSRD at a rise-rate of about 20 A/ns, the DSRD itself can be used to pulse another DSRD at a rise-rate of about 60 A/ns. An enhanced performance by the proposed method, resulting in a high-voltage nanosecond pulse has been reported. This pulse was then further sharpened by driving a fast avalanche diode. A 6-kV, 130-ps rise-time, with a rise-rate exceeding 40 kV/ns circuit is presented.
