Title: Wave-packet propagation in tokamak plasmas: basic elements.
Abstract: Wave-packet propagation investigation is useful for construction of global mode structure and its time evolution in tokamak plasmas. Its main relevant techniques are presented in this talk. First, the general flux coordinates system is introduced, from the analytical model to numerical equilibrium from experiment. Second, Mode Structure Decomposition (MSD) method is demonstrated, from its mathematical foundation, Poisson Summation Formula, to its connection with Ballooning Formulism. Last, its application to lower hybrid wave propagation and ion temperature gradient mode structure is revisited.
