We present a theoretical description of different types of accretion disks and jets near supermassive black holes (SMBHs) that can be observed in a (sub)millimeter wave band. Special attention is paid to a possible formation of an image (a shadow) of a black hole illuminated by an accretion disk or a jet. We suggest a simple criterion of detection of such a shadow in the current and planned SMBHs observations employing the method of Very Long Baseline Interferometry (VLBI). As an example, we propose a number of potential SMBHs candidates satisfying this criterion for observations with the future "Millimetron" space observatory in the VLBI regime as well as with the Event Horizon Telescope (EHT).
