Web Reference: This is a COMSOL tutorial for replicating band diagram result of the hexagonal photonic crystal from from the paper "Scheme for Achieving a Topological Photonic Crystal by Using... Jan 22, 2018 · In this paper we study topological phases in a two-dimensional photonic crystal with broken time (𝒯) and parity (𝒫) symmetries by performing calculations of band structures, Berry curvatures, Chern numbers, edge states, and also numerical simulations of light propagation in the edge modes. See the triangular, FCC, BCC photonic crystal bandstructure example for more information on simulating Hexagonal / Triangular lattices. To run the three parameter sweeps: Gamma-M, M-K, K-Gamma, and to plot the results, run the Planar3D_hex.lsf script file.
