Figure 8: Demonstration of a trivial insulator phase.
From: Probing topological protection using a designer surface plasmon structure
(a) Simulated band diagram of the topologically trivial designer surface plasmon structure. (b) Simulated field pattern of bulk state at 11.3 GHz. (c) Simulated field pattern at 11.45 GHz in the bandgap. (d) Observed field pattern at 11.3 GHz in the bulk band. (e) Observed field pattern at 11.45 GHz in the topologically trivial bandgap. Metal is modelled as a perfect electric conductor in simulation.
