Abstract: In the present work, we propose a theoretical model to describe a cubic lattice of resonators with bianisotropic response based on dyadic Green's function approach. The effects of the bianisotropy parameter value on the dispersion diagram are investigated and topological properties of the system are considered by calculating the Berry curvature distributions for three different planes.

Keywords: topological insulators, bianisotropy, dyadic Green’s function, Berry curvature.
