Abstract:Formerly, microwave emissions accompanying hypervelocity impacts were confirmed experimentally. In this paper, two kinds of analyses, output waveform analysis and spectral analysis, are discussed for the purpose of clarifying the mechanism of microwave emissions. In output waveform analysis, the microwave pulse is simulated on the basis of a microcrack model in consideration of discharge current, and is compared with the experimental pulse in terms of the pulse shape. In spectral analysis, the amplitude and ph… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
