New steps toward the development of a microwave axial tomomograph for inspecting dielectric materials are reported in this paper. The design of the proposed imaging system is described and the results of preliminary forward scattering simulations are reported in order to define the requirements for an efficient treatment of the measured scattered data.

In this paper, an experimental set up based on interrogating microwaves is used to obtain images of the cross section of dielectric cylinders. In particular, a microwave tomographic configuration is used to inspect wood slabs in order to search for defects and voids. The measured data (samples of the scattered electric field) are inverted by...

A new prototype of a tomographic system for microwave imaging is presented in this paper. The target being tested is surrounded by an ad-hoc 3D-printed structure, which supports sixteen custom antenna elements. The transmission measurements between each pair of antennas are acquired through a vector network analyzer connected to a modular...

Nondestructive testing and evaluation techniques able to extract information about the internal structure of the samples under test are very important in the wood industry. Microwave imaging systems have been considered for a long time promising apparatuses for this task. In this framework, approaches exploiting the full scattering phenomena...
