Imaging of dielectric targets with metallic inclusions by means of a prototype of microwave axial tomograph

Microwave systems are becoming powerful tools for imaging applications. In fact, when designed by taking into account the full scattering phenomena, they are able to directly provide information about the physical properties of the target under test. In this paper, the possibility of detecting metallic inclusions inside dielectric objects is assessed by using a prototype of a microwave axial tomograph, which is able to create images of the dielectric permittivity and of the electric conductivity of the inspected target.
