Simulation of Resonator Slow-Wave Structures and Terminal Devices of TWT Sections in SHF and UHF Ranges
P. 1–5.
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.

This paper discusses the modeling of the process of interaction in traveling-wave tubes (TWTs) based on 'coaxial-radial line'-type (CRL-type) slow-wave structures (SWSs). One of the most important tasks while designing TWTs is to achieve high output power over wide range of frequencies. The aim of this paper is to try to solve this problem by ...

In this paper, dispersion characteristics of "serpentine”-type slow-wave structures, which are promising for the terahertz range use, are calculated. For 3D-modeling, HFSS was used. Program described in work was used in the calculation. Using the obtained characteristics, octopole chain model of the slow-wave structure is constructed. Discrete approach is advisable in solving these problems. Justification ...

При разработке усилителей сверхвысоких частот (СВЧ) большой и средней мощности, широко используемых в радиоэлектронном приборостроении, применяются цельнометаллические резонаторные замедляющие системы (ЗС), обеспечивающие необходимый теплоотвод. Эти ЗС являются трехмерными, а моделирование приборов, создаваемых на их основе с использованием строгих электродинамических программ, требует больших затрат вычислительных ресурсов. Поэтому разработка простых и точных моделей резонаторных ЗС, используемых при ...
