A general three-dimensional transformation optics approach is presented that yields analytical expressions for the relevant electromagnetic magnitudes in plasmonic phenomena at
singular geometries. Specifically, this powerful theoretical tool enables us to reveal the broadband response and superfocusing capabilities of touching nanospheres and dielectric loaded crescent
shaped nanoparticles. In this contribution, an elegant and complete physical description of the optical properties of these two plasmonic geometries will be provided.
