Scattering of ECRF waves by edge density fluctuations and blobs

open access: yesEPJ Web of Conferences, 2015
The scattering of electron cyclotron waves by density blobs embedded in the edge region of a fusion plasma is studied using a full-wave model. The full-wave theory is a generalization of the usual approach of geometric optics ray scattering by blobs ...
