Abstract
An omnidirectional photonic band gap (OBG) realized by one-dimensional Fibonacci quasiperiodic structure which is composed of plasma and two kinds of isotropic dielectric is theoretically studied. From the numerical results performed by the transfer matrix method (TMM), it has been shown that the frequency range and central frequency of OBG cease to change with increasing Fibonacci order, but vary with the thickness and density of the plasma. The bandwidth of OBG can be notably enlarged. It has also been proved that Fibonacci quasiperiodic one-dimensional ternary plasma photonic crystals (PPCs) have a superior feature in the enhancement of OBG frequency range compared with the conventional ternary PPCs.
