Analytic Study of Propagation and Absorption of Nearly Perpendicular Injected Electron Cyclotron Ordinary Wave

摘要

Electron cyclotron resonance heating (ECRH), such as the fundamental heating and the second harmonic heating, is a basic and powerful method to heat the plasma in tokamak and stellarator devices. Theoretical studies of this heating has been done in rather early literatures, however, the understanding of some important problems is still uncertain. These include: the coupling of the O-mode and the E-mode and the role of this coupling in wave damping, the O-mode damping mechanism,
