中文摘要：

利用光子晶体的共振隧穿效应，并结合由负折射材料引起的零平均折射率带隙，设计出一种新型的角度滤波器，使得对于某一频率范围内的入射电磁波仅在特定入射角度的波能够全透，而其他角度的波不能透过．这将在微波器件乃至光学器件上有广泛应用．

英文摘要：

A new kind of one-dimension photonic crystal （PC） which can be used as an angular filter was studied. With the knowledge of resonance tunneling mechanism in zero average index PC, we find such PC must contain negative refractive metamaterials and its structure parameters should satisfy some special conditions. When electromagnetic wave of a given frequency incident on such PC, only those portions with incident angles identical with the special angle （or angles） can pass through such PC, while the others can not. Such filter would have wids applications in microwave and optical communications.
