Abstract
A systematic study of the omnidirectional reflection range of one-dimensional photonic crystals with a staggered structure is presented, based on numerical simulations performed with the well-known transfer-matrix method without any simplifying assumptions. We determined that the excellent performance of the crystals extends the range of omnidirectional reflection. We redefined the structure by employing two structural parameters and found that they play different roles in bandgap broadening, which is useful for practical design. The relations between the omnidirectional reflection range and the two structural parameters are presented in detail.
