TL;DR: In this paper, the dependence of the loading resistance on the target plasma parameters, operational regimes and synergic heating scenarios on EAST is reviewed, and the antenna coupling resistance R c in L-mode regime meets the relation of R c ∝ exp(−1.5k ∥ x c), which is in good agreement with the simulation results with a perfectly matched layer method, where k ∥ is the dominant launched parallel wave number and x c is the distance of the ICRF antenna and fast wave cutoff layer.
