摘要

We report that tunable omnidirectional total reflector can be realized theoretically with one-dimensional (1D) photonic crystals (PCs) by adding external magnetic fields. The 1D PCs consist of two alternating layers with SiO_2 and InSb. We show that the 1D PCs have rather large omnidirectional photonic band gaps (omni-PBGs). After being added external magnetic fields the omni-PBGs will be tuned accordingly. The shift ranges of left and right circular polarizations are different. As a result, the omnidirectional reflector and omnidirectional circular polarizer can be realized.
