Popis: Full-wave simulations are performed in order to investigate the interaction of plasma density perturbations and microwaves. The perturbations are divided into two cases: A single blob-like structure and a fully turbulent density profile. The resulting scattering of a microwave beam and the effect on the O–X mode conversion are presented for both cases. Quantitative analyses are performed as a function of the average size and position of the perturbations. The usage of spatial coordinates normalized to the vacuum wavelength of the microwave allows to easily adopt the results to a specific problem.
