【 摘 要 】

Transformation optics, a geometrical recipe for metamaterial design, was originally conceived as a tool to smoothly modify the trajectory of light using continuous coordinate transformations. Here, we show how discontinuous transformations can be used as a geometric framework to understand and manipulate phenomena at the surface of nanophotonic structures. In particular, we show how the Goos-Hanchen shift-a lateral shift exhibited by totally reflected beams-can be tailored and we provide a classification and complete analytical description of this effect in existing complex media.
