Resonant Modes of Disk-Loaded Cylindrical Structures With Open Boundaries
Autor: Ioannis Chelis, J.L. Vomvoridis, Konstantinos A. Avramidis
Publikováno v: IEEE Transactions on Microwave Theory and Techniques
Disc-loaded cylindrical structures are found in many microwave devices and components, which in some cases need to be studied as open resonators. The electromagnetic formulation and analysis presented involves the use of a generalized mode-matching t

Post-Amplification of a Gyrotron RF Beam by a Sheet Electron Beam
Autor: J.L. Vomvoridis, Giorgos Anastassiou
Publikováno v: IEEE Transactions on Plasma Science. 38:1208-1218
The availability of high-power microwave sources like gyrotrons makes it now possible to use the Gaussian output RF beam of a conventional gyrotron propagating in free space as an input for the interaction with a sheet electron beam (e-beam) drifting
