Abstract

Reflection and transmission coefficients in stratified chiral media are presented for EM oblique plane-wave incidence, based on the 4×4 transfer-matrix method. The photonic band gap properties of one-dimensional layered periodical structures that include of double negative material, so-called backward-wave (BW) material are investigated. The relation between photonic bandgap and chirality admittance has been analyzed. The simulation results show that the width of the PBG in the structure composed of chiral medium and BW medium is larger than that composed of chiral medium and usual medium. Our analysis has shown that the usage of the negative material makes it possible to dramatically widen the band gap of one-dimensional photonic crystal.
