Simulation of Resonator Slow-Wave Structures and Terminal Devices of TWT Sections in SHF and UHF Ranges

Abstract

In this paper, the models of the rectangular and axially-symmetric slow-wave structures (SWSs) are considered. These models are used to calculate the dynamic transient response of SWSs. In order to calculate the traveling-wave tube (TWT) section parameters, the waveguide-resonator model and the regression models are utilized. The section terminal devices are simulated by the characteristic impedance of semi0infinite chain of coupled cavities. The developed models serve as the basis of the program complex "VEGA" development.
