| Abstract: | We consider multiple scattering of electromagnetic waves by a layer of turbulent magnetized collisional plasma. The influence
of the distances from the layer's boundaries to the emitter and receiver is analyzed. We find out that, provided absorption
in the plasma is strong enough, the width of the angular spectrum of the received radiation can be larger than in the collisionless
plasma, and the maximum of the spectrum is substantially shifted with respect to the direction to the source. It is shown
that these effects weaken as the emitter approaches the layer. The dependence of the width of the spectrum and the shift of
its maximum on distance from the receiver to the layer's boundary can be substantially nonmonotonic.
