Abstract: The subject of the seminar is to present recent investigations on wave propagation in complex networks made by hubs and connections. The word “complex” refers to a twofold attribute: a large numbers of hubs, and a large number of interconnections between the hubs. Propagation of classical waves takes place within an elemental topological connectivity scheme. In a complex connection topology, the concept of phase and group velocity changes dramatically, and new properties emerge. Several examples recently investigated by the author of non-conventional connectivity are presented, ranging from metamaterials to platoons of autonomous robots. Special effects as wave stopping and superluminal propagation are discussed. Finally, some perspectives related to the concept of Small World conclude the presentation.
