Abstract
The design of resonant cavities, aimed at obtaining a desired electromagnetic field configuration, must take into account the geometry and the coupling between the cavity itself and the transmission line delivering the electromagnetic power to the structure. The design issues are even more challenging when the cavity is filled with an inhomogeneous and anisotropic medium. In this paper, we present an electromagnetic analysis, carried out by multiphysics simulations with COMSOL Multiphysics® and MatLab®, of conventional (cylindrical) and unconventional geometries for resonant cavities containing magnetically confined plasmas. The study has been applied in particular to Electron Cyclotron Resonance Ion Sources, with the aim at improving their performances.File | Dimensione | Formato | |
