Modeling the spectral modification of lower hybrid wave in the presence of drift-wave type density fluctuation in the scrape-off-layer of the EAST tokamak

Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'The spectrum change of lower hybrid (LH) waves caused by low-frequency density fluctuation in the scrape-off layer (SOL) is studied by applying the wave scattering model developed by Bonoli and Ott [Bonoli and Ott, Physics of Fluids 25, 359 (1982)] via a Monte Carlo method. Due to the influence of density fluctuation, the perpendicular component of the LH wave-vector can be rotated in the 2D perpendicular space, which will further change the ray trajectory of the LH wave. A ray-tracing model specific to this purpose is developed to evaluate the probability distribution of both poloidal refractive index (N_theta) and the parallel refractive index (n||) of the LH wave at the last closed flux surface (LCFS), assuming wave propagation through the turbulent SOL plasma from the launcher at the far SOL to the LCFS.
