Unusual transmission bands are found in one-dimensional photonic crystals composed of alternating layers of positive-index materials and single-negative (permittivity- or permeability-negative) materials. By varying the thicknesses of the positive-index material layers, the number and central frequencies of these transmission bands can be tuned. On the other hand, by varying the thicknesses of the single-negative material layers, only the bandwidths of these transmission bands will change. Furthermore, omnidirectional transmission bands for TE or TM polarization can be realized from these periodic photonic structures.
