| Abstract: | Propagation of electromagnetic waves in one-dimensional (1-D) stratified chiral structures is described by the 4×4 transfer-matrix
method. The photonic bandgap (PBG) properties in 1-D periodical chiral media are investigated. The relation between PBG and
chirality admittance has been analyzed. Under proper operating parameters, quite perfect multichannel filtering properties
can be obtained with the periodic structure. The photonic bandgap properties of one-dimensional layered periodical structures
that include of double negative (DNG) medium, so-called backward-wave (BW) medium are investigated. The simulation results
show that the width of the PBG in the structure composed of chiral medium and BW medium is larger then 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.
