Kinetic Full Wave Analysis of Electron Cyclotron Wave Mode Conversion in Tokamak Plasmas

Abstract

By employing the integral formulation of dielectric tensor, we have introduced the kinetic full wave analysis of ordinary-extraordinary-Bernstein (O-X-B) mode conversion in tokamak plasma in one dimension on the basis of TASK/W1 code using the finite element method. The boundary value problem of Maxwell's equation is solved and the finite Larmor radius effects are represented by integral formulation. The O-X-B mode conversion and the absorption near the cyclotron harmonic resonance are successfully described.
