(a) Mass density for computation of the diffraction pattern for the case (the black stripe model). Black dots represent point masses of equal mass. Gray lines are guides for the eye. The point masses touching the dashed blue lines form the level-2 unit cell. (b) Total computed diffraction pattern for levels 1–6 of the mass decoration. The largest wave vectors shown correspond to the basis vectors of the reciprocal lattice associated with the undecorated hexagonal tiling.
(a) Region of the mass density for computation of the diffraction pattern for the mass decoration. Black and light gray (light purple) disks represent point particles of equal mass . Darker gray (darker purple) disks represent particles of mass . (b) Total computed diffraction pattern for levels 1–6 of the mass decoration. The largest wave vectors shown correspond to the basis vectors of the reciprocal lattice associated with the undecorated hexagonal tiling.
