  The paper demonstrates the possibility to use ANSYS HFSS as a versatile
simulating tool for antennas facing inhomogeneous anisotropic magnetized
plasmas in the Ion Cyclotron Range of Frequencies (ICRF). The methodology used
throughout the paper is first illustrated with a uniform plasma case. We then
extend this method to 1D plasma density profiles where we perform a first
benchmark against the ANTITER II code. The possibility to include more complex
phenomena relevant to the ICRF field in future works like the lower hybrid
resonance, the edge propagation of slow waves, sheaths and ponderomotive forces
is also discussed. We finally present a 3D case for WEST and compare the
radiation resistance calculated by the code to the experimental data. The main
result of this paper - the implementation of a cold plasma medium in HFSS - is
general and we hope it will also benefit to research fields besides controlled
fusion.
