Abstract
The ability to mould the flow of light to the largest possible extent at will is a promise that can be met with metamaterials (MM). MMs are artificial structures made of periodically arranged unit cells. It is possible to attribute effective properties to the medium, if the unit cells are such small that light will not resolve the spatial details but merely experience an effectively homogenous medium. Whereas a significant portion of research was devoted to elucidate the principles of MMs and to identify unit cells that affect either the effective properties, less research was devoted to the question which manifest applications can be realized with MM. Here we present an example with a metamaterial nanotip [1].
