Abstract: Transformation optics has recently emerged as a powerful and systematic approach to design application-oriented metamaterials. In this letter, following up on our previous studies on thin planar retroreflectors, we show how it is possible, in principle, to design "transformation medium" coatings capable of controlling the scattering response of metallic corner- and wedge-type structures so as. e.g., to strongly enhance the specularly reflected component. We validate our results via a full-wave study of the near- and far-field responses, and envisage possible applications.
