A program is written to calculate the scattering parameter of vacuum tubes' window. The Finite Differential in Time Domain (FDTD) method was applied with stair mesh approximation in the program. A coaxial waveguide window was simulated. And the S11 parameter calculated is in consistent with the CST MWS results.
In this paper, the first analytical model to compute the dispersion of the double-corrugated waveguide for THz vacuum devices is presented. The model is based on the definition of voltage profile between two pillars in a single period. The comparison of the model with 3D electromagnetic simulation demonstrates the validity of the approach.
Microwave Tube Simulator Suite (MTSS) is a full-featured software package for microwave tube analysis and design. Recent developments to the MTSS in last year will be presented.
Summary form only given. Microwave Tube Simulator Suite (MTSS) is a full-featured, tightly integrated software package for microwave tube analysis and design. It includes a friendly user interface module and three physics simulators. Microwave Tube Design Environment (MTDE) is the user interface module, which provides a powerful solid modeling front-end and graphical and computational post-processing...
Recent developments to the electron optics simulator (EOS), an electron gun and collector design tool, are reported in this present. The code has been formally released at 2007, and there are some modifications and new methods to improve the code up to now.
In this paper, an optimization algorithm has been developed to provide robust designs for nonlinear beam-wave interaction of high-frequency traveling-wave tubes (TWTs). The algorithm utilizes the optimization method of hybrid genetic algorithm (Goldberg, 1990) in the TWT simulation code which is much like CHRISTINE-1D (Antonsen, 1998). By considering the effects of dimensional helix pitch variations...
