The composites with opposite signs of the dielectric permittivity in two orthogonal directions, known as the hyperbolic metamaterials, represent a new "universality class" of optical media, with the light behavior which is qualitatively different from that in either metals or dielectrics. Propagating waves in such "electromagnetic hyperspace" do not suffer from the diffraction limit on the optical resolution, leading to the hyperlens - the device capable of producing magnified far-field images of subwavelength objects, while the broadband super-singularity of the photonic density of states in hyperbolic media results in a dramatic change in a variety of phenomena, from spontaneous emission to light propagation and scattering.
