Abstract
The rotation angle of the static magnetic field compared with the toroidal direction should not be ignored for many ion cyclotron range of frequency (ICRF) antenna designs. The antenna coupling code based on the variational theory is employed to analyze the influence of the rotation angle of the static magnetic field on the ICRF antenna coupling on EAST theoretically. A comprehensive analysis of the variation of the coupling resistance dependent on the rotation angle is under taken. The shift of the power spectra as a function of parallel and perpendicular wave numbers is analyzed. The variation of the current distributions also supports the conclusions associated with the ICRF wave coupling. The results and conclusions in this paper will benefit the ICRF antenna design and the experiments relevant to the ICRF wave coupling.
