Rectangular Grating Slow-Wave Structure With a Slot Embed Electron Beam for High-Power Terahertz Radiation

To enhance the output power of 0.5-Terahertz (THz) backward wave oscillator (BWO), a grating loaded rectangular waveguide (GLRW) slow-wave structure (SWS) with a slot embed electron beam (SEEB) is proposed in present work. For the designs and optimizations of BWO GLRW SWS with SEEB, the dispersion equations are derived with a field matching method (FMM) and solved by a numerical method; the result...
