Since the discovery of the Quantum Hall effect and, consequently, the topo??logical states, the interest for devices exploiting this kind of phenomena has grown significantly. These types of state are characterized by a surprising en??ergy localization resulting in a high-quality factor. In the first part of this work, some possible topologies presented can be used to induce the creation of edge and corner states. With FEM simulations, in particular COMSOL, the disper??sion relations of the single cells and supercells have been studied both in 2D and 3D. The topological states have been induced because of the breaking of the symmetry in specific directions.
