摘要

Basing on the condition that the incident angle is larger than the total internal reflection angle, we present a systematic study of transmission properties of one-dimensional photonic crystal with all dielectric materials by the transfer matrix method and the Bloch's theorem. Due to the existence of the evanescent field within the structure, the transmission bands consist of some discrete symmetry peaks. For light with these peak frequencies, the structure is either transparent or opaque depending on the number of the structure periods. The unusual transmission properties are attributed to the field distribution and Bloch wave vector.
