ENHANCEMENT OF THE DEFECT FIELD OF ONE-DIMENSIONAL PHOTONIC CRYSTALS CONTAINING ε- AND μ-NEGATIVE LAYERS

Employing the transfer matrix method, we study the electromagnetic field of one-dimensional photonic crystals with a defect inserted by pairs of mu-negative (MNG) and epsilon-negative (ENG) material layers. The fields within the pairs of layers and the matrix defect are independent of each other, and the whole field is their superposition. The whole defect field can be significantly enhanced by pairs of epsilon-negative and mu-negative layers. In contrast to the conventional defect modes, the intensity and volume of the defect field with pairs of epsilon-negative and mu-negative layers can be precisely adjusted.
