- Abstract
The focusing property of electromagnetic wave is investigated by a flat slab made of octagonal photonic quasicrystal. We obtain polarization-independent focusing by use of the all-dielectric photonic quasicrystal. The influence of geometrical factors of photonic quasicrystal on the focusing property for TM and TE polarizations is explored in detail. The results show that two orthogonal polarizations have a common focus point only under certain proper condition. Our results may be a useful guidance for the fabrication of lens devices capable of polarization-independent focusing by photonic quasicrystal.
