Fig. 1. (a) Unit cell where the gray surface is a cut plane along
Fig. 2. (a) Unit cell where
= 77.31°; (b) the first Brillouin zone where blue dots and red dots represent, respectively, the Weyl points of different chirality; (c) the numerically calculated band structure, where shaded region denotes the frequency range with only Weyl degenerate bands appears.
Fig. 3. (a)−(d) Band structure with
= 90°, 81.18°, 77.31° and 60°, respectively. The inset is the top view of meta-atom, and the shaded region denotes the frequency range with only Weyl degenerate bands appears.
Fig. 4. (a) Two cut planes in the first Brillouin zone where the yellow plane represents the plane of
= 0.432 and the dashed line denotes the intersecting line of two planes; (b) the projected bulk bands (grey curves) and the associated
surface state (blue and red curves) at
= 0.432; (c) the magnitude of
