Description:Finite Element Electromagnetic Analysis of TWT Slow-Wave Structures in Grid Environment
Abstract:The simulator is written in C++. Its structure follows the classical scheme of FE simulators in which three main modules are present. The first one groups pre-processing functions (such as the construction of the geometrical and functional model and FE mesh generation). The second module is devoted to the processing functions (solution of the mathematical model). The last module is devoted to post-processing (such as further elaboration of results, analysis plots, etc.). The tool has been specifically conceived to provide the TWT designer with an easy-to-use environment through a friendly CAD-based Graphical User Interface (GUI). Differently from other interfaces dedicated only to post-processing, it aims at facilitating the management of all the various aspects of a simulation session, allowing the interactive execution of all the simulator functions
The GUI also includes visualization tools, together with some specific pre/post-processing functions related to TWT design and global parameters extraction, including the automatic building of the Brillouin diagram, from which the phase velocity is evaluated.
