    Densely packed metasurfaces composed of cylindrical silicon nano-resonators were found to demonstrate the phenomenon of electromagnetically induced transparency at electric dipolar resonances. It was shown that this phenomenon is not related to overlapping of dipolar resonances or to the Kerker’s effects. The observed transparency appeared to be related to interference between waves scattered by nano-resonators and by additional scattering centers including the electric branch of lattice resonances. Coupled resonance fields were also found to contribute to observed phenomena.

    The possibility of replacing metamaterials in transformation media by lossless dielectric photonic crystals is investigated. It is shown that such crystals are capable of both accelerating waves to superluminal phase velocities and bending wave paths around the objects thus providing initial wave front reconstruction beyond the objects. To realize transformation optics prescriptions for the cloak medium, we propose to use crystals with rectangular unit cells. We show that these crystals can provide prescribed anisotropy of directional indices along crystallographic directions.

    Realization of the full potential of transformation optics depends on access to the media, in which prescribed by the theory spatial dispersion of material parameters, such as permittivity, permeability and/or refractive index, could be implemented. As an alternative to conventional metamaterials, this work presents transformation media composed of all-dielectric metamaterials and photonic crystals.
