Kaliteevski, M.A. and Brand, S. and Abram, R.A. (2004) 'Directionality of light transmission and reflection in two-dimensional Penrose tiled photonic quasicrystals.', Journal of physics : condensed matter., 16 (8). pp. 1269-1278.
We have investigated the directionality in the reflection and transmission spectra of Penrose-type photonic quasicrystals. In the frequency interval considered, there are two omnidirectional stopbands. It is found that for the low-frequency stopband light is reflected ballistically, while for the higher-frequency band reflected light is scattered with a change in wavevector equal to one of the reciprocal lattice vectors associated with the first stopband. The relationship between the intensities of the ballistic and the scattered reflected and transmitted light suggests that two-dimensional quasicrystals possess an omnidirectional photonic bandgap for the E and H polarizations.
