Tools and techniques for microwave imaging and sensing

Microwave imaging and sensing provide non-invasive tools for investigation of the unknown structure or properties of regions of interest. These techniques are used in scenarios where different materials have different eletromagnetic (EM) properties, or where changes in a material may be identified through EM property variations. The diverse range of applications includes ground-penetrating radar for inspection of roadbeds, medical microwave imaging and characterization of water content of materials. Common to all of these applications is the need for reliable and effective collection of data, as well as a means for translating these data into meaningful results. The main objective of the proposed research program is to develop a flexible microwave imaging system that provides sensitive and specific images using multiple, low-cost sensing technologies.
