Abstract

We found that a whole class of structures with rhombohedral symmetry possesses sizable photonic gaps. These structures can be generated by connecting lattice points in an A7 structure by cylinders and a few structures that are known to possess photonic band gaps are in fact members of this ‘‘parent’’ structure. This class of structures also allows us to explore more systematically the criteria favorable for gap formation.
