摘要：
During its design phase, the JET ITER-Like ICRF antenna array has been modeled in great detail with the 3D electromagnetic software CST MICROWAVE STUDIO(R). The resulting rf field and current density patterns have guided the optimization of the antenna feeder shapes, leading overall to a strong reduction (similar to25%) of the maximum electric field, and to a factor-of-three reduction of the inhomogeneity of rf current at the matching capacitors. The computed frequency response of the array is now used in matching studies and development of a control algorithm. Comparison with the experimental frequency response of the High Power antenna Prototype developed by ORNL and PPPL shows fair agreement.
