Design and simulation of a 0.2-THz traveling-wave tube with a converging sheet electron beam

Development and Modeling of Miniaturized Traveling-Wave Tubes in Millimeter and Sub-THz Bands

“…2. The design was verified by 3-D simulation using LO-RENTZ-3EM simulator [6]. The results are in a fairly good agreement, except that the beam thickness obtained in 3-D analysis is somewhat higher than expected (~75 um) that can be attributed to thermal and angle spread of the emitted electrons.…”
