We employ our AMR (Antenna—Mode-conversion—Ray-tracing) code to calculate the O-X-EBW conversion efficiency with a full-wave equation solver, while the power deposition and current drive profiles using ray tracing. EBW current drive was theoretically predicted and experimentally detected at 2.45 GHz.
