| Multiple structures in one-dimensional photonic crystals have great potentials for ultrawide omnireflectors and tunable switches. In this paper, we study the propagation of electromagnetic waves in a one-dimensional heterostructure magnetic photonic crystal for both TE and TM incidence polarizations by means of the transfer matrix method. Results show that by stacking two magnetic photonic crystals as a heterostructure magnetic photonic crystal the omnidirectional total reflection frequency range for any polarization enlarged due to overlapping of photonic band gaps of both magnetic photonic crystals. Omnidirectional band gaps in the heterostructure magnetic photonic crystal is enhanced rather than that in a single magnetic photonic crystal. |
