Solution of electromagnetic inverse problem of inhomogeneity reconstruction in dielectric body by near-field measurements using two-step method

Background. The inverse electromagnetic problems of restoring inhomogeneity in a dielectric body from near-field measurements arise, for example, in the early diagnosis of breast cancer by microwave tomography. The solution of such inverse problems is the basis for the development of technology for detecting inhomogeneities using microwave devices. The effectiveness of the corresponding technology depends on the accuracy of solving the inverse problem. Therefore, the development of new, more accurate methods for solving the inverse problem of microwave tomography is very relevant.
