title: Resonance cones in cylindrically anisotropic metamaterials: a Green's function analysis.
abstract: A Green's function analysis for cylindrically anisotropic media is presented that can be used in the design of various metamaterial devices. The resonance cones, which describe the direction of power flow, result from the Green's function singularity when the permittivity tensor elements have opposite signs. Shadow and accessible regions for the source are also identified.
