Thèmes abordés
Wireless systems have become ubiquitous and new technologies exploiting higher frequencies, with wider bandwidths, are reinforcing this trend. This calls for a deeper understanding of high-frequency electromagnetic fields, as they occur in microwave circuits and propagation problems.
Regarding microwave circuits, an advanced study of guided waves appears necessary, taking into account the quite diverse types of transmission lines and the study of their dispersion analysis. This may include dispersion-engineered materials, such as metamaterials.
Regarding propagation, spatial selectivity is becoming more intensively used, since phased arrays now fully entered the civilian domain, in both communication and radar front-ends. This calls for spatial-spectrum representation of fields, in Cartesian, cylindrical and spherical systems of coordinates. Those will also be applied to propagation problems, including for instance surface waves. A link with optics will be made, through the analysis of partially coherent fields, which are more thoroughly studied in optics than in microwaves.
An introduction the different types of numerical methods for field analysis, including commercially available software, will be provided as well.
The exposed concepts will also be put in practice through different labs, devoted mainly to guided waves and radar experiments.
