Simulation of Lower Hybrid Wave Propagation in EAST

A simulation on the propagation of lower hybrid wave in EAST is conducted. Ray tracing, evolution of the parallel refractive index, and power deposition profiles in a D-shaped configuration were calculated. Results show that wave propagation is affected by the plasma current, density, magnetic field, and power spectrum, etc. leading to a different power deposition. This is helpful in understanding the LHCD experiments on EAST. (brief communication and research note)
