Abstract

Resonance cones, the regions where major power and high-intensity fields are concentrated, form with cylindrically anisotropic media when the permittivity tensor elements have opposite signs. The resonance cones inside a circular layer of cylindrically anisotropic material is shown to experience multiple internal reflections from the layer boundaries. We introduce a spectrometer class by exploiting the dispersive properties of a metal-insulator stack metamaterial. The cones can exhibit negative refraction at the interface of two such circular layers, leading to a far-field bilayer subwavelength imaging system with more flexibility in the material parameter and operating wavelength spaces.
