15. Simulations were performed using the package CONCERTO 4.0, developed by Vector Fields Ltd, England (2004). In our simulations, a basic cell sized 0.5 mm × 0.5 mm × 1 mm is adopted to discretize the space. Finer sub-meshes were adopted in space regions where strong inhomogeneity exists

17. In both TE and TM excitation cases, we find that the in-plane electric dipoles are induced on the metallic patterns, which further couple to the metal sheet to form magnetic responses
18. We find that the Bragg scatterings introduced by the periodic planar metallic patterns are not strong enough to open the gap
