Standard approaches to reproduce the coupling of wave propagation and plasma transport inside a helicon plasma source rely on electromagnetic simulations coupled to either kinetic or particle-in-cell strategies to reproduce the plasma response. If the plasma density reach values higher than 10^17 m^-3, these approaches would result in a computational burden, therefore we have adopted a fluid strategy to reproduce the plasma transport. We have developed a tool that consists of two software that study separately the wave propagation and the plasma transport, respectively ADAMANT and the Plasma module of COMSOL Multiphysics®; the reciprocal influence of these two phenomena is grasped coupling the two software through an iterative loop implemented with the LiveLink™ for MATLAB®.
