我们研究利用外部磁场操纵磁光子晶体（MPC）中的电磁波。我们预测了新的巨磁反射效应和巨磁折射效应：在比铁磁体各向异性场小得多的外部磁场下，MPC可以从完全反射变为不反射，并伴随折射角的相应变化。还讨论了电磁辐射存储的应用。
We examine manipulating electromagnetic waves in magnetic photonic crystals (MPCs) with external magnetic fields. We predict new giant magnetoreflectivity and giant magnetorefractivity effects: with an external magnetic field of a magnitude much smaller than the anisotropy field of the ferromagnet, the MPC can be changed from completely reflecting to nonreflecting with corresponding changes in the angle of refraction. Application to the storage of electromagnetic radiation is also discussed.
