Enormous progress is being made in developing observational facilities. As a result, there are new opportunities to observe structures at sub-mas resolution. To explore gravitationally lensed systems, we simulate radio-lobe images distorted by microlensing. We show that the positions of ‘holes’ in lensed images may indicate the positions of microlens groups or overdensities.
