• Dispersion and energy relations of ion cyclotron wave for a cold plasma are systematically studied retaining the electron mass. In this case, two wave modes having different perpendicular wave numbers can exist in a uniform plasma column. The dominant mode is a quasi-TE mode, in which the plasma current j_z is an important quantity. Because this current is carried by electron motion along the static magnetic field, the dispersion relation and energy relations are considerably modified for light mass ions compared with the customary one in which the electron mass is neglected. Plasma loading for a coil excitation of the Stix type is also considered using this dispersion relation. The electric field, magnetic field, energy density, and energy flow are calculated based on the quasi-TE mode. The energy losses due to cyclotron damping and collisions are also summarized. Here a possible mechanism due to resistivity is pointed out.
