Query: Experimental realization of epsilon-near-zero metamaterial slabs with
  metal-dielectric multilayers   Epsilon-near-zero (ENZ) metamaterial slabs at visible frequencies based on
metal-dielectric multilayers are experimentally realized. Transmission,
reflection and absorption spectra are measured and used to determine the
complex refractive indices and the effective permittivities of the ENZ slabs,
which agree with the results obtained from both the numerical simulations and
the optical nonlocalities analysis. Furthermore, light propagation in ENZ slabs
and directional emission from ENZ prisms are also analyzed. The accurate
determination of the ENZ wavelength for metal-dielectric multilayer
metamaterial slabs is important for realizing many unique applications, such as
phase front manipulation and enhancement of photonic density of states.
