Abstract
Dynamic changes in helicon wave structure, due to excitation by a helical antenna, are investigated as a function of time. Before a density jump (steep density increase), not a propagating wave but a standing wave near the antenna is found. After the jump, a selective helicon wave excitation of azimuthal mode numbers m = 1 and m = - 1 is demonstrated, and the first the energy flux estimate shows different axial profiles for the two modes.Keywords
