Аннотация:
Excited wave characteristics in a large-diameter plasma produced by a planar spiral antenna are investigated. Radial and axial profiles of the excited magnetic fields, a dispersion relation and observing regions of the excited magnetic fields are studied, for variations in the filling pressure and the static axial magnetic field; successful excitation of the propagating helicon wave with an azimuthal mode number of m = 0 is shown.
