Identification of Inhomogeneities from Far Field Data

Inhomogeneous media identification is the problem of determining the physical properties of an unknown inhomogeneity from its response to various interrogating modalities. This response, recorded in measured data, comes as a result of the interaction of the inhomogeneity with an exciting physical field. Inhomogeneous media identification is mathematically modeled as the problem of determining the coefficients of some partial differential equations with initial or boundary data from a knowledge of the solution on the measurement domain.
