A diagram showing both a hyperlens using a realizable rolled-up TiO₂/Ag structure (a) and one using the effective permittivity theory (b). Objects being imaged are λ/30, separated by a distance of λ/2. (c) Using material combinations which result in anisotropy with characteristics of Re{ε_r}⪢Re{ε_θ}, elliptical dispersion, or Re{ε_r}<0 and Re{ε_θ}>0, hyperbolic dispersion, allow for the transmission of subwavelength information. (d) The elliptical dispersion relation curves for a TiO₂/Ag 5:1 ratio structure are plotted, showing a lens which is capable of transmitting subwavelength information over the entire visible spectrum.

The anisotropic range of a hyperlens with different ratios of oxide to metal is presented (Al₂O₃/Ag plot overlaid on TiO₂/Ag plot). (a) The tunable hyperbolic dispersion range (solid color with bars) is defined to be where Re{ε_r}<0 and Re{ε_θ}>0, given the criteria for the hyperlens effect and elliptical dispersion range (solid color), which is defined as Re{ε_r}⪢Re{ε_θ}. The dotted lines are the wavelengths required for impedance matching (Z_match) the given metamaterial lens with air, whereas the dashed are those required for matching with water, which result in a high transmission into the far field. (b) The dispersion relation for different material makeups is shown at different wavelengths in the visible spectrum. This illustrates the fact that the dispersion relation, whether hyperbolic or elliptical, is relatively flat, which results in high resolution of high order spatial information.
