Abstract

We fabricated a 3D photonic crystal consisting of metal coated disk-shaped magnetic particles floating at the liquid-air interface inside a stack of containers. The particles self-assemble into an ordered crystal whose in-plane lattice constant can be varied by external magnetic field in very broad limits. This crystal exhibits photonic stopband at microwave frequencies. The stopband can be continuously tuned by external magnetic field until complete disappearance.
