2D kinetic full wave analysis in magnetized plasmas using the integral form of dielectric tensor

In order to describe the wave structure and power deposition profile in hot magnetized plasmas, full wave analysis based on the integral form of dielectric tensor has been extended to various configurations. The integral form of the dielectric tensor includes two types of kernel functions, the Plasma Dispersion Kernel Function (PDKF) and the Plasma Gyro Kinetic Function (PGKF). Recently PDKF was extended to parabolic magnetic field profiles in order to describe the cyclotron resonance near the magnetic field extremum. The extended finite element method including the coupling of elements along particle orbits is used. First the behaviour of cyclotron waves near the field extremum is examined and compared with the results of geometrical optics. The newly extended two-dimensional full wave code, TASK/WF2D, has been applied to the analyses of ion cyclotron wave heating in large tokamaks, lower hybrid current drive in middle-size tokamaks, O-X-B mode conversion of electron cyclotron waves in small tokamaks, and ion cyclotron resonance heating in axisymmetric mirror configurations.
