PERIOD: FEBRUARY-MARCH Microwave imaging technology exploits the differences in dielectric properties of the objects under test. The area under analysis is illuminated, at microwave frequencies, with low-power electromagnetic (EM) waves radiated by an array of antennas placed around. The resulting scattered EM fields are recorded by the same antennas and processed with suitable algorithms to translate them into images. Microwave tomography (MWT) has attracted increasing interest in recent years as an alternative diagnostic tool for medical imaging. Among the various applications, the diagnosis of breast cancer and brain stroke is undoubtedly the most prominent example. Low cost, reduced equipment size, and the use of low intensity and non-ionizing radiations make MWT particularly appealing compared to standard diagnostic tools for brain strokes. Techniques such as magnetic resonance imaging (MRI) and x-ray computerized tomography (CT) are much more expensive, bulky, and potentially harmful for the patient or operator. MWT can be considered as a cooperation technique to make diagnosis or follow-up more accurate and comfortable. In the food industry, there is also an increasing interest in MWT techniques. Detecting food contamination in products moving along the production chain is a priority for every established food producer. Although detection technologies have been widely used in the last years, low-density foreign bodies such as plastic, thin glass, or wood are still undetectable to all established detection systems but are identifiable through dielectric properties differences. Low cost and non-ionizing radiations make this technique appealing also for industrial scenarios. The course aims to give the students the necessary tools to understand and design MWT systems, select the best application approach and propose new techniques. The course structure covers a general introduction and applicability of the method, the theoretical concepts, and the already existing devices. The final examination will face students with theoretical and practical problems, exploring other possible application scenarios in their fields.
