TL;DR: A first-principles full-wave model, using conditionally sampled 2D electron density profiles, predicts fluctuations of the millimeter-wave power that are in agreement with experiments.

TL;DR: In this paper, the authors show that the measured plasma density fluctuations in the upper part of the scrape-off layer (SOL) are the cause of fluctuations of the transmitted mmw-power.

TL;DR: In this article, the scattering of millimeter-wave beams from electron density fluctuations and the associated beam broadening are experimentally demonstrated using a dedicated setup, instantaneous deflection and (de-)focusing of the beam due to density blobs on the beam path are shown to agree with full-wave simulations.
