Abstract :
The energy and defect mode properties of one dimensional ternary photonic crystals with left-handed medium (LHM) were investigated by transfer matrix method. It was demonstrated that the transmission became tunable, depending on the thickness and the refraction index of the slabs deeply: as the thickness of LHM slab in the structure became wider, the Bragg gap shifted toward higher frequency, in sharp contrast to its shifted toward lower frequency as a result of widening the thickness of positive-index-material slab. Moreover, it was found that the defect mode is sensitive to the thickness of the defect layer and it could be controlled by changing the thickness of the defect layer.
