Abstract: A backward-wave oscillator (BWO) is an intense electromagnetic source based on an interaction between an electron beam and a backward wave. In this study, a surface wave is excited as a ...
Back in 1966, a suitable toy for a geeky kid was a radio kit. You could find simple crystal radio sets or some more advanced ones. But some lucky kids got the Philips Electronic Engineer EE8 Kit ...
Abstract: A dual-band (DB) metamaterial (MTM) is investigated for the study of a DB MTM-based backward wave oscillator (DB-MTM-BWO). The MTM-based electromagnetic (EM) structure, i.e., the ...
