Higher-symmetric waves: dispersive engineering

We aim at relating dispersive properties of artificial materials with relevant symmetries and explain them in terms of degenerate points and symmetry properties of the modal fields. Different symmetry conditions can provide different polarizations, anisotropic or non-reciprocal effects. We want to investigate the possibility to engineer desired frequency dispersions by introducing suitable symmetric/asymmetric conditions.
