  • quasistructonly.pdf and quasistructonly.ai : Icosahedral photonic quasicrystal
      the world's first and largest 3d icosahedral photonic quasicrystal (composed of polymer) and the largest quasicrystal model (in terms of number of units) ever constructed

  • quasi3.pdf and quasi3.ai : Montage of three images
      the icosahedral photonic quasicrystal (white polymer structure);
      the first-ever visualization of the Brillouin zone of a 3d quasicrystal (ring with yellow lines indicating nearly symmetrical zone boundaries);
      a microwave transmitter used in the measurements.
