Three-dimensional electromagnetic modeling of the ITER ICRF antenna (external matching design)

Abstract

The present work reports on 3D radio-frequency (RF) analysis of a design for the ITER antenna with the CST Microwave Studio® software. The four-port junctions which connect the straps in triplets have been analyzed. Non-TEM effects do not play any significant role in the relevant frequency domain, and a well-balanced splitting of current between the straps inside a triplet is achieved. The scattering matrix has also been compared with RF measurements on a scaled antenna mockup, and the agreement is very good. Electric field patterns along the system have been obtained, and the RF optimization of the feeding sections is under way.
