Abstract

Slow wave structure supporting the beam-wave interaction in a relativistic backward wave oscillator (BWO) requires a carefully designed output waveguide in order to couple the electromagnetic wave to a radiating antenna. The coupling between these two sections determines the quality factor (Q) of the slow wave structure and affects the starting current and the saturation processes occurring when the electron beam is injected into the device. The goal of this paper is to study the end reflection and quality factor of a practical slow wave structure both experimentally and theoretically. Consequently, the outcome was summarized in a simple analytic form, which shows good agreement with experiment over all resonant frequencies.
