High-resolution electromagnetic imaging in a plain layered structure

Problems of detection and localization of electromagnetic sources in a dielectric layered medium is considered in this paper. As it is shown interfaces of the layer medium has significant influences on formation of scattered field. To solve the problem, it is proposed to use combination of high-resolution approach to localization of sources and conception of dyadic Green function for a layer medium. In case of near field observation, the parameter content of high-resolution Capon's method was modified to obtain better spatial resolution of sources when scattered field is measured by a linear array at multiple frequencies.
