In sub-THz communication systems, compact, high-power, tunable radiation sources are
required. Backward wave oscillators (BWO) have been practical devices for THz …

A 660 GHz high-order mode operation backward wave oscillator (BWO) is proposed based
on a novel composite structure. The fundamental mode oscillation can be suppressed by …

A coalesced-mode, wide bandwidth traveling wave tube (TWT) with a large beam tunnel is
herein investigated for use in millimeter-wave and terahertz amplification sources. The high …

This article introduces a radial rectangular concentric grating (RRCG) backward wave
oscillator (BWO). The design utilizes a radial sheet electron beam (RSEB). It aims to …

In this article, an experimental investigation has been carried out to analyze the breakdown
characteristics of a pseudospark (PS) discharge-driven sheet electron beam source. A …

The output power of a backward wave oscillator (BWO) is limited by the low interaction
impedance of a slow wave structure (SWS) when the frequency is in the THz band. A BWO …

With the increased interest in Terahertz applications and technologies there is a growing
demand of new and improved transmitters. Spectrum analyzers are frequently used to …
