Abstract

Two-dimensional finite-element method analysis is performed for ICRF antennas having various cross-sectional configurations. The main interests are focused on the quantitative difference in the input impedance among various antennas such as the normal loop antenna, the antenna having surrounding limiter walls, and the antenna buried into cutoff cavity. For analytical simplicity, the cold plasma approximation is used. The numerical results show how the input impedance was affected by the presence of the limiter walls or the cutoff cavity. The code described in this paper can be applied to the designs of ICRF antennas with a wide range of plasma parameters and antenna geometries.
