Wave trajectories and cyclotron damping of the electromagnetic waves (O- and X-modes) and the electron Bernstein wave (B-mode) propagating in three dimensional toroidal plasmas are investigated, assuming the geometrical optics. Electron cyclotron heating (ECH) by injection of O- and X-mode is effective in low density (\(\omega_{\text{pe}}{ }\varOmega_{\text{e}}{\approx}\omega\)), where B-mode is linearly converted from X-mode or O-mode (the latter being converted to X- and then to B-mode). Because of strong damping, B-mode is also useful for low T e plasmas. Propagation characteristics and mode-conversion in these high density plasmas are studied in detail.
