Abstract: The main goal of this project was related to the efficient and accurate calculation of the complete modal spectrum of rectangular cavities loaded with cylindrical dielectric resonators. To understand the behaviour of these elements, and to determine its best coupling mechanism for filtering applications, it is necessary to determine the electromagnetic field distribution inside the dielectric-loaded metallic cavity. This project was based on the application of a very efficient method developed at the University of Pavia (Italy) by the research group of Prof. Giuseppe Conciauro. This method is called BI-RME (Boundary Integral-Resonant Mode Expansion), and it has been very efficiently applied to the analysis of many other complex microwave circuits. The BI-RME method has proved during last years to be a great contribution to the electromagnetic theory being a very flexible and accurate tool for the electromagnetic characterization of arbitrarily shaped microwave devices. However, BI-RME has been employed so far to the analysis of metalllic perturbations present in waveguides and cavities, but it has never been applied to the analysis of dielectric obstacles. In this sense, this work is a very important contribution to the electromagentic theory, just providing the possibility to extend the BI-RME technique to the analysis of dielectric inhomogeneties in both waveguides and cavities in combination with the existing theory efficiently applied to the treatment of metallic obstacles. It also involved a strong collaboration between the University of Pavia, the Technical University of Valencia and the University of Valencia in the development of passive microwave devices advanced CAD tools based on the BI-RME method.
