|Optical concentrator from a hyperbolic liquid crystal metamaterial|

We examine the optical properties of two different configurations (circular and radial field) of cylindrical device made from a hyperbolic metamaterial, that is a medium for which the ratio between ordinary and extraordinary permittivities is negative. Comparison between a simple geometrical optics treatment and wave formalism shows that the concentration of light along the cylinder axis occurs whatever their injection condition are.
