Energy dissipation in helicon plasma at the near field of an antenna
The results of a computer simulation of energy dissipation in helicon plasma at near field of an antenna are presented. Results are reported for a double-half-turn antenna, and comparison is made to a double-saddle-coil antenna which demonstrates the distinct inductive and helicon-wave modes. The...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The results of a computer simulation of energy dissipation in helicon plasma at near field of an antenna are
presented. Results are reported for a double-half-turn antenna, and comparison is made to a double-saddle-coil
antenna which demonstrates the distinct inductive and helicon-wave modes. The computer simulation revealed a
significant wave-particle interaction in the near-field of the antenna that is less than half wavelengths from the
antenna. Namely, in addition to the ohmic heating from the currents induced by the helicon wave, electrons can
become trapped in the traveling helicon wave via the resonance condition. |
