title: Subwavelength imaging opportunities with planar uniaxial anisotropic lenses.
abstract: The imaging properties of a uniaxial anisotropic slab lens, where the dielectric tensor components are of the opposite sign, are studied as a function of the structure parameters. While hypothetical parameters yield various levels of performance, a design principle to achieve good subwavelength resolution is suggested. The anisotropy can be implemented with a metal-insulator stack.
