Nonlinear Reactive Circuits Driven by Magnetic Flux Compression Generators.

摘要

Presently, generators of broadband microwave radiation, using spiral magnetocumulative generator (MCG) as the energy source, are under intensive investigation [1,2]. In the majority of the existing designs, researchers are attempting to generate high-power radiation over a the broad spectral range by directly connecting the MCG to an antenna or by using the helical coil of the MCG as the radiating element [2,3]. These are called direct drive devices. It is understood that the efficiency of these devices is very low, which is attributed to the impossibility of matching the energy source, with output characteristics that change in time, with antenna sizes no greater than tens of centimeters and to the fact that the characteristic length of the MCG current pulse, driving the antenna, ranges from 10-7 to 10-6 s.
