Optimization and Parallelization of Ray-tracing code for microwave propagation in Tokamak plasmas
Background and motivationElectron Cyclotron Resonance Heating (ECRH) systems inject high-power millimeter waves into magnetically confined plasmas to provide localized heating and, when needed, current drive. In tokamaks, the effectiveness and safety of ECRH depend strongly on how the beam propagates through an inhomogeneous, magnetized medium: refraction, mode evolution, and absorption determine the deposited power profile,
