Simulations of RF wave propagation in hot magnetized (2H) plasma in DTT Scenario

An analytical model and numerical simulations of the propagation and absorption of radio-frequency waves in hot magnetized (2H) plasma are pre- sented. First, an investigation of the impact of thermal effects on the dispersion relation of the waves has been conducted by expanding the hot plasma dielectric tensor to the first order in temperature. Second, starting with the realistic Ion Cyclotron Heating (ICH) antenna model designed for the Divertor Tokamak Test project, a simple 1D (1-dimensional) model of the wave propagation has been devel- oped. The antenna’s spectra have been extracted and analyzed using CST , and the 1D wave propagation has been performed through MATLAB .
