(a) Trihexagonal uniform tiling and (b) [36;32.4.3.4] 2-uniform tiling, and their corresponding high air-filling structures. (c) Band diagram of the [36;32.4.3.4] structure, green and red curves are the band diagrams of the square and triangular apexes, respectively. Bandgaps of the square and triangular structures (see Fig. 3) are shown in black bold. Figure inset shows the structures’ band diagram within the effective index range of \(1\pm 0.01\).
