Kaliteevski, M.A. and Brand, S. and Abram, R.A. and Krauss, T.F. and DeLa Rue, R. and Millar, P. (2000) 'Two-dimensional Penrose-tiled photonic quasicrystals : from diffraction pattern to band structure.', Nanotechnology., 11 (4). pp. 274-280.
We report measurements of the diffraction pattern of a two-dimensional photonic quasicrystal structure and use the set of plane waves defined by the diffraction pattern as the basis of a theoretical approach to calculate the photonic band structure of the system. An important feature of the model is that it retains the essence of the rotational and inflational properties of the quasicrystal at all levels of approximation: properties lost in approximate models which artificially introduce elements of periodicity. The calculated density of modes of the quasicrystals is found to display a weakly depleted region analogous to the bandgap that occurs in a periodic system. The calculated transmission spectra for different polarizations and directions of propagation show features that correlate with the behaviour of the density of modes.
