Photon tunnelling in one-dimensional metamaterial photonic crystals

Photon tunnelling in a metamaterial photonic crystal composed by positive index material (PIM) and negative index material (NIM) layers is discussed. First, a single period of this photonic crystal is considered as the barrier in a frustrated total internal reflection (FTIR) structure, and the transmittance, the post-tunnelling position shift and the group delay time of different frequency incident waves through the barrier are calculated. In the case of a barrier of more periods of photonic crystal, the transmittance and the group delay time also vary with layer number, which are analysed in detail.
