The cylindrical corrugated-wall metal waveguide with an axial magnetized degenerate plasma rod is proposed for sub-millimeter and terahertz vacuum device. The dispersion characteristics of symmetric electromagnetic TM-modes in the device is analyzed. The investigation results show that the corrugated-wall waveguide with an axial magnetized degenerate plasma rod would be a promising slow-wave structure...
Using the simple unified theory, the beam-wave interactions are analyzed in high-power Cerenkov-type microwave generators composed of periodic metal slow-wave structure (SWS) with a magnetized plasma column.
An approach to the enhancement of Cherenkov radiation source driven by two electron beams (TEBs) is presented in this paper. The Cherenkov radiation source is composed of a cylindrical grating, and TEBs with a velocity separation are concentric and separated. By a field matched method, the dispersion equation is derived with a linearized fluid theory and solved by numerical calculation. The numerical...
