Microlensing Effects in Atmospheres of Substars

The purpose of the present work is the study of focusing properties of atmospheres of substars that is necessary for adequate interpreting of observational data and for solving the inverse problem consisting in recovery parameters of ‘microlenses’ (substars) and sources (quasars). Amplification factor for a quasar image as projected onto the field of microlenses-substars was computed for optical and radio wavelengths.
