A new structure of RF control of plasma for electric propulsion has been proposed. With excitation characteristics of a helical antenna and propagation characteristics of waves with rotating field, both plasma production and ion heating will be expected simultaneously by employing a single helical antenna. Basic experiments to examine the proposed structure have been performed, showing consistent results with expected scenario.
