Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty Of Engineering - Department Of Electronics and Communications Summary: Reconstruction of permittivity profiles plays an important role in electromagnetic inverse scattering problems which have numerous applicationsExamples of these applications are : the geophysical applications which are used to predict earth constituents and biomedical applications which help in diagnosis of abnormal tissues in the human bodyDifferent algorithms have been investigated to perform the one dimensional inverse problem both in time and frequency domainsSuccessive modifications of these algorithms are given in the time domain using the non - linear Ricatti differential equation in a linearized formThis linearization is achieved by renormalizing the reflection coefficient in such a way to enable the direct reconstruction of the permittivity profile with the aid of the Fourier Transform in the planar structures and Hankel transforms in the cylindrical structures

Reconstruction of permittivity profiles plays an important role in electromagnetic inverse scattering problems which have numerous applicationsExamples of these applications are : the geophysical applications which are used to predict earth constituents and biomedical applications which help in diagnosis of abnormal tissues in the human bodyDifferent algorithms have been investigated to perform the one dimensional inverse problem both in time and frequency domainsSuccessive modifications of these algorithms are given in the time domain using the non - linear Ricatti differential equation in a linearized formThis linearization is achieved by renormalizing the reflection coefficient in such a way to enable the direct reconstruction of the permittivity profile with the aid of the Fourier Transform in the planar structures and Hankel transforms in the cylindrical structures
