A novel two-step electromagnetic imaging method, suitable for the analysis of hidden inclusions in dielectric structures, is reported in this paper. In particular, two distinct steps compose the present technique. The first one extracts from the raw data an estimation of the scattered field due to the inclusions, and provides a first...

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...

Despite the numerous advancements in the field of microwave measurement systems and techniques for biomedical and industrial applications, the development of cheap and reliable microwave imaging devices is still a challenge. In this contribution, a tomograph prototype specir1cally designed for medical imaging is presented. An array of custom...

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...

Temperature monitoring during the cooldown in powder bed fusion of polymers is essential to qualify parts, and is an absolute novelty in the field. This is because the direct reading of the parts' temperature is hindered by the powder. In this work, an innovative temperature monitoring technology based on microwave tomography is used to assess...

An existing prototype of microwave imaging tomograph, previously designed by the present Authors for non destructive testing (NDT) applications, has been adapted in order to deal with biomedical targets. The developed system allows collecting multi-view multi-frequency data. An efficient inversion procedure is used to retrieve the distributions...
