“…This section provides the LTSpice circuit simulation results using models developed by Pouladian-Kari et al [9], Weiner and Silber [12], and Dolan and Bolton [13], and a comparison with the corresponding results found in them, respectively. Also for validation of the results, Dolan and Bolton's [13] model is reproduced using a numerical analysis method compared with the LTSpice circuit simulation.…”

“…As pointed out by Dolan and Bolton [13], the model proposed by Pouladian-Kari et al [9] is not complete, since the So far, the best way to simulate these lines was through the method proposed by Dolan and Bolton [13], since they used this model to simulate the output response of a line with azimuthal and also with axial bias. In this model, they used an equivalent circuit based on the elements of a discrete LC transmission line in series with instantaneous voltage sources (see Fig.…”

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.

Gyromagnetic Nonlinear Transmission Lines (NLTLs) generate microwaves through the damped gyromagnetic precession of the magnetic moments in ferrimagnetic material, and are thus utilized as compact, solid-state, frequency agile, high power microwave (HPM) sources. The output frequency of a NLTL can be adjusted by control of the externally applied bias field and incident voltage pulse without physical alteration to the structure of the device. This property provides a frequency tuning capability not seen in many conventional e-beam based HPM sources. The NLTLs developed and tested are mesoband sources capable of generating MW power levels in the L, S, and C bands of the microwave spectrum. For an individual NLTL the output power at a given frequency is determined by several factors including the intrinsic properties of the ferrimagnetic material and the transmission line structure. Hence, if higher power levels are to be achieved, it is necessary to combine the outputs of multiple NLTLs. This can be accomplished in free space using antennas or in a transmission line via a power combiner. Using a bias-field controlled delay, a transient, high voltage, coaxial, three port, power combiner was designed and tested. Experimental results are compared with the results of a transient COMSOL simulation to evaluate combiner performance.
