摘要：There is an increasing interest to have an access to hidden object s without making any destructive action. Such non-destructive method is able to give a picture of the inner part of the structure by measuring some external entities. The problem of reconstructing planar multilayered structures based on given scattering data is an inverse problem. Inverse problems are ill-posed, beside matrix inversion tools, a regularization procedure must be applied additionally. Multiplicative regularization wa s considered as an appropriate penalty method to solve this problem. The Gauss-Newton inversion method as a n optimization procedure wa s used to find the permittivity values, which minimize d some cost functions. Several dielectric layers with different thickness and profiles we re observed. Some layers need ed more discretization elements and more iteration steps to give the correct profiles.
