Abstract
The S-matrix of mock-up ICRF antennas and the ASDEX Upgrade antenna were measured and compared with the commercial code HFSS ™ , designed to calculate electromechanical properties of structures, and with FELICE, written to calculate the coupling of ICRH antennas to a warm plasma in slab geometry, but also usable for calculating antenna properties without plasma. Proper assessment of the boundary conditions led to excellent agreement between the measurements and the results of HFSS for a wide range of antennas. Good agreement between the measurements and the calculations with FELICE was found for those cases were the actual antenna geometries and those that could be implemented in FELICE were not too different. © 2003 American Institute of Physics [ABSTRACT FROM AUTHOR]
