The deteriorating effect of plasma density fluctuations on microwave beam quality
Alf Köhn, Max E. Austin, Michael W. Brookman +13
Turbulent plasma edge density fluctuations can broaden a traversing microwave beam degrading its quality. This can be a problem for scenarios relying on a high spatial localization…
Microwave beam broadening due to turbulent plasma density fluctuations within the limit of the Born approximation and beyond
Alf Köhn, Lorenzo Guidi, Eberhard Holzhauer +4
Plasma turbulence, and edge density fluctuations in particular, can under certain conditions broaden the cross-section of injected microwave beams significantly. This can be a seve…
Influence of plasma turbulence on microwave propagation
Alf Köhn, Eberhard Holzhauer, Jarrod Leddy +2
It is not fully understood how electromagnetic waves propagate through plasma density fluctuations when the size of the fluctuations is comparable with the wavelength of the incide…
Full-wave modeling of the O-X mode conversion in the Pegasus Toroidal Experiment
Alf Köhn, Jonathan Jacquot, Michael W. Bongard +3
The ordinary-extraordinary (O-X) mode conversion is modeled with the aid of a 2D full-wave code in the Pegasus Toroidal Experiment as a function of the launch angles. It is shown h…
