For the 2.45 GHz the mode conversion could be investigated in detail by HF-probes. The propagation of the EBW´s was calculated by a 3D- ray-tracing code for both 2.45GHz and 28 GHz. The results were confirmed by the measurement of the local resonant power deposition with the power modulation technique. The predicted EBW driven toroidal current for the 2.45 GHz could be clearly detected experimentally by total and local measurement.
