Figure 2 | Schematic illustration of Robinson triangle decomposition method and geometrical structure factor.

Caption

a Robinson triangle decomposition method and characteristic distance of the quasicrystal array. The RA and RB are thin and thick Penrose rhombuses with 36° and 72° vertex angles, respectively. And d is the side length of the rhombus. The TA, TA’, TB, and TB’ are Robinson isosceles triangles. b Schematic setup of the radiating dipole. r is the vector from the origin O directing to the observation P. θn is the rotation angle of the Penrose rhombus. c Reciprocal vector of our quasicrystal metasurfaces.
