Abstract :
A steady-state large signal model of the beam-wave interaction in a folded or serpentine waveguide traveling-wave tube is described. The model used a three-port network representation of the circuit and a 1-D disk model of the beam. Values of the admittance elements that characterize the model are identified with a 3-D finite element code, HFSS. This model can be used to simulate the beam-wave interaction in other types of slow-wave structures.
