Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how ...
Abstract: In this article, we propose a low reflection folded waveguide (LRFWG) as the slow wave structure (SWS) for the development of a terahertz (THz) traveling-wave tube (TWT). Our simulation ...
Years ago, the process of faculty evaluation carried few or none of the sudden-death implications that characterize contemporary evaluation practices. But now, as the few to be chosen for promotion ...
