Learning Outcomes
Upon the successful completion of the course, the students would have acquired the following skills: - To comprehend the non-destructive testing basic principles and categorization of the basic flaws due to fabrication, processing, and use of specific apparatuses. - To assimilate the concepts of microwave aquametry as a non-destructive technique for the evaluation of moisture in specific structures and analyze the dielectric properties of various media. - To design, parametrically analyze, develop, fabricate and measure a prototype measurement system, as part of a laboratory project. Specifically, they will be able to perform the required theoretical analysis of the involved electromagnetic phenomena, to construct the prototype by means of specialized laboratory procedures, to simulate the prototype through several computational methods, and obtain sample measure for a variety of real-world scenarios. - To familiarize themselves with advanced laboratory facilities and equipment and the development of certain numerical techniques for the simulation of the designed prototypes.
