摘要: A systematic study of the photonic band gap (PBG) properties 8-, 10- and 12-fold rotational symmetric quasicrystals (QCs) defined by level set equations with various phase parameters is reported. The optimized filling ratios corresponding to largest PBGs for 19 types QCs are found, which useful QC fabrication design. impact ratio, symmetry, experimental on resultant studied via PBG maps calculated finite-difference time-domain (FDTD). Large area, high quality 10-, quasicrystalline pattern using multiple exposure interference lithography (MEIL) also demonstrated.
