    We demonstrate a novel artificial optical material, a "photonic hyper-crystal", which combines properties of hyperbolic metamaterials and photonic crystals. It is based on cobalt nanoparticle ferrofluid subjected to magnetic field.
    Bandgap properties of one-dimensional superconducting photonic crystals containing metamaterials are investigated by the transfer matrix method. It is shown that the low-frequency band gap can also be present in this superconducting photonic crystal similar to the usual superconducting photonic crystal containing dielectric materials. The low-frequency band gap can be widened considerably when the suitable structure parameters are chosen. However, in certain structural parameters, the low-frequency band gap can not be found in this superconducting photonic crystal just as in one-dimensional dielectric-dielectric photonic crystal. The polarization properties and the influences of the operating temperature and the structure parameters of superconducting photonic crystals on the photonic band gap are also investigated in this paper.

    We introduce a new "universality class" of artificial optical media - photonic hyper-crystals. These hyperbolic metamaterials with periodic spatial variation of dielectric permittivity on subwavelength scale, combine the features of optical metamaterials and photonic crystals.
    In article number 1800198, Kiumars Aryana, Mehdi B. Zanjani and co-workers predict novel colloidal superstructure phases that can be built through self-assembly of complex colloidal molecules. The resulting multielement structures provide a unique platform to design photonic and phononic metamaterials with a wide range of tunable transport properties.
