Abstract

Simulations of realistic RF antennas have been performed with the finite element analysis software package COMSOL both with dielectric media and cold plasma loading. Results are presented from simulations with a finite (low) plasma density in the antenna box and ITER like density profile in front of the antenna. First steps were made to introduce the presence of sheaths by means of a non-linear boundary condition. Output characteristics such as scattering parameters and fields have been compared with results from CST Microwave Studio® and the TOPICA code. Good agreement has been found, which illustrates the potential of the present COMSOL-based modeling to benchmark antenna codes. Furthermore non-linear conditions can be imposed on boundaries, which is important for sheath effect modeling.
