摘要：
In this paper, a time-dependent nonlinear theory including the generalized time-dependent radiofrequency (RF) field equations is presented to simulate the beam and wave interaction (BWI) of folded waveguide (FWG) traveling wave tubes (TWTs). The analytical RF fields in FWG TWTs are replaced by digitized RF field profiles obtained from electromagnetic simulations. A W-band FWG TWT is studied by using a self-consistent one-dimensional code based on the theory. The numerical results show good predictions when compared with the experimental tests.
