Outline of Final Research Achievements

In order to analyze electron cyclotron heating and current drive in high-density regime of tokamak plasmas, integral-form of dielectric tensors required for kinetic full wave analyses in inhomogeneous plasmas was formulated. The obtained formula were applied to one-dimensional full wave analyses in unmagnetized plasmas, magnetic mirror configuration, and hot plasmas with finite gyro radius effects to show their wide applicabilities. This scheme was applied to the quantitative analysis of mode conversion to the electron Bernstein waves in tokamaks. Profiles of wave electric field and power deposition density were obtained and it was confirmed that the parameter dependence of antenna loading resistance is consistent with analytic estimation.
