The wave coupling simulation result of ICRF antenna in J-TEXT relying on the perfectly matched layer technique

In order to test the performance of the ion cyclotron range of frequencies (ICRF) antenna of the J-TEXT tokamak, a coupling model between ICRF wave and plasma is established using finite element method. The model is configured with cold plasma dielectric tensor, flat straps and perfectly matched layer (PML) which is used to emulate radiating boundary conditions beyond a critical cutoff layer for the fast wave. 2D and 3D coupling models are constructed to complete a preliminary analysis of the antenna.
