COMSOL has been used to model the propagation of electromagnetic waves in fusion plasmas. For the first time, a finite element method has been used to solve the wave propagation for realistic fusion plasma parameters in the lower hybrid and ion cyclotron frequency ranges. Moreover, for lower hybrid waves, a new efficient iterative algorithm has been developed to take into account the dispersive effects of a hot plasma. The advantages of the finite element method approach include a significant reduction of computational requirements compared to full wave spectral methods and a more accurate description of the antenna geometry, while seamlessly handling the plasma region.
