Abstract: In this paper, possibilities of multifrequency microwave diagnostics of dielectric inhomogeneities in media with a strong absorption are studied. At that, experience with a similar system that has been worked for diagnostics of low-absorbing media is in use. Algorithms of tomography and holography based on the solving the inverse problem of near-field scattering that have been applied in data processing are modified in application to new parameters of strongly absorbing media and studied in the numerical simulation.

Key words: tomography, holography, dielectric, inhomogeneous media, scattering of microwave radiation.
