We followed this program during the course 1996-1997, and we give several examples of the kind of exercises that we used. We also present some remarks and conclusions that we have achieved in our experience. Our purpose is to introduce a teaching strategy for Mathematics and Physics at the University level.

The complex band structures obtained by solving for the k(ω) problem reveal a complete interpretation of the propagation properties of these systems. The prediction of evanescent modes, nonpredicted by classical ω( k) methods, is of interest for the understanding of these propagation properties. Complex band structures provide an interpretation of the evanescent coupling and the level repulsion states showing the possibility of controlling evanescent waves in periodic materials. DOI: 10.1103/PhysRevB.84.212302 PACS number(s): 43.20.Fn, 43.20.Gp, 43.20.Mv, 63.20.−e Propagation of waves in periodic structures is characterized by both propagating and evanescent waves. On one hand, the control of the propagation properties of periodic electromagnetic 1-3 and elastic 4-7 materials has revealed a huge number of physical phenomena in the last decades. On t...

These materials suppress the acoustic scattering in the long wavelength regime, being rather disordered and degenerate, while possessing a wide band gap. In this work, these hyperuniform materials are made of an air-filled acoustic waveguide with rigid diaphragms acting as scatterers. A wide band gap and the emergence of the edge modes provide promising applications in wave control devices.
