摘要：In radio bands, the study of compact radio sources can be affected by propagation effects introduced
by the interstellar medium, usually attributed to the presence of turbulent intervening
plasma along the line of sight. Here, two of such effects are presented. The line of sight of
B 2005+403 passes through the heavily scattered region of Cygnus causing substantial angular
broadening of the source images obtained at frequencies between 0.6GHz and 8GHz. At higher
frequencies, however, the intrinsic source structure shines through. Therefore, multi-frequency
VLBI observations allow to study the characteristics of the intervening material, the source morphology
and the interplay between them in forming the observed image.
