• Wave traJectories and cvclotron damr>ins of the electromasnetic waves (0- andX-modes) and the electron Bernstein wave (B-mode) propagating in three dimen-sional toroidal plasmas are investigated, assuming the geometrical optics. Electroncyclotron heating (ECH) by injection of 0- and X-mode is effective in low density(co..<0.ta), high electron temperature T. plasmas in large tori. Here, cto,., f2.,and ctc are the electron Langmuir, cyclotron and the applied freque?acies, respec-?tively. On the other hand, B-mode is effective for ECH on high density plasmas(co..>.Q.ti), where B-mode is linearly converted from X-mode or 0-mode(the latter being converted to X- and then to B-mode). Because of strong damping,B-mode is also useful for low T. plasmas. Propagation characteristics and mode-conversion in these high density plasmas are studied in detail.
