A special kind of photonic crystal and enlargement of omnidirectional total reflection band

Abstract

A special kind of one-dimensional magnetic photonic crystal (MPC) with the same refractive indices of the composites is investigated. We adopt the transmission matrix method to analyze the transmission properties of the special MPCs. The results indicate that the stop-band edges of TE mode coincide with those of TM mode, and the stop bands for both modes expand as the incident angle increases. Based on the incident angle domain method, the ODTR band determined by the wave impedance ratio can be enlarged using a heterostructure. Moreover, the requirement of ODTR of each sub-PC is unnecessary, which extends the range of materials.
