Abstract:
Background In the fields of high-power microwaves and pulse compression, compared with exponentially decaying microwave pulses, the flat-top output has core advantages such as reducing the maximum transient surface field of the structure and enhancing system stability. Therefore, it has significant technical significance and application value.
Purpose The purpose of this study is to develop a new method for power doubling that generates a flat-topped output and to observe its benefits through simulation experiments.
Methods The research analyzes the energy storage process and the power gain and flat-top output width after input inversion based on the scattering matrix theory, and conducts simulation experiments using CST.
Results The simulation experiment results show that its power gain is more than 5.7 times, the flat top width is 80 ns, the waveform is gentle, and the power capacity can reach 160 MW.
Conclusions Compared with the existing technology, this design has a simple structure, compact volume and convenient processing and maintenance, providing a new solution for the stable output of high-power microwave energy and the research of two-stage pulse compression systems.
