Two algorithms for image reconstruction in electromagnetic imaging are proposed. The first approach concerns the application of a hybrid version of the genetic algorithm to tomographic imaging of dielectric configurations. In the second approach, buried inhomogeneities are schematized as multilayer infinite dielectric cylinders with elliptic...

The application of the differential evolution method in two important areas of applied electromagnetics is discussed in this chapter. The first one refers to the synthesis and design of array antennas, for which differential evolution, as well as other evolutionary algorithms, is now considered a fundamental design tool. The second one concerns...

In nonlinear inverse scattering problems, induced contrast sources are often used to model the response of the scatterers under test to the interrogating incident field. They then constitute, together with the contrast function (which includes the parameters of interest of the object under test) the problem unknowns. In this paper, an approach...
A simple and efficient method for data inversion in microwave imaging is proposed. The approach is based on the inverse scattering theory. The measured data are related to the dielectric properties of the object under test by the well-known Lippmann-Schwinger integral equation. The second-order Born approximation is applied in order to...
In this paper an Inexact Newton method is applied to solve the electromagnetic inverse scattering problem. Such algorithm is composed by two nested loops: in the outer one the nonlinear scattering equations are linearized and in the inner one the linearized equation is solved by means of a truncated Landweber method. In particular, the...

A global optimization procedure for the detection of buried inhomogeneities is extended to the case of multiple illuminations. The object inhomogeneities are schematized as multilayer infinite dielectric cylinders with elliptic cross sections. A recursive analytical procedure is used for the computation of the forward scattering. A functional...
