Abstract :
In this paper, the authors present a finite element tool expressly conceived for the analysis of TWT helicoidal SWSs. The tool includes a dedicated mesh generator, an eigenmode and a driven mode solver, and a post-processing module. Examples of typical SWS analysis performed by using the tool are also given
