Abstract

This study is aimed at the solution of the inverse problem used for determining the inhomogeneity of an object. The scattered field is measured beyond its limits with a certain set of observation points. It is assumed that the radiation source and the observation points are located outside the object under investigation. The scattered field is modeled as the result of solution of the direct problem. For solving the inverse problem, a two-step method is employed. The application of various types of nonlinearities is considered. The computational grid is introduced using the generalized grid method. A numerical method for solving this problem is proposed and implemented. The numerical results reported here demonstrate the solution to the problem for preset experimental data.

期刊介绍: Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
