This paper describes the progress made in recent years in addressing the technological challenges that must be met to achieve high power microwave sources for a variety of purposes. Efforts are underway to increase the pulse width and power of high power microwave sources. Research in narrow band sources has progressed toward the junction of high power and conventional tube technology. Ultra-wide band technology is at present focused on a ...
Gallium arsenide photoconductive semiconductor switches (PCSS) are being studied as enabling technologies for a variety of applications. High grain PCSS can be triggered with small laser diodes or laser diode arrays. Some of the applications require low temporal jitter of the switches relative to the trigger laser. The purpose of this study was to compare the temporal switch jitter times for different systems: we varied the type of trigger laser ...
Recent advances in the understanding of dynamical systems and chaotic behavior have resulted in the investigation of HPM source design issues. Modern dynamical systems theory can improve our understanding of the dynamics of space charge dominated beams and the RF waveforms generated by them. This paper will review the work done to date using time series analysis techniques to study the state space dynamics of high power microwave sources using ...
