Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields—electric displacement field D, magnetic induction field B, and Poynting vector B—are all displaced in a consistent manner. A simple illustration is given of the cloaking of a proscribed volume of space to exclude completely all electromagnetic fields. Our work has relevance to exotic lens design and to the cloaking of objects from electromagnetic fields.

• Nonlinear waves in PT -symmetric systems (2016, positive): “The idea (Leonhardt, 2006; Pendry, Schurig, and Smith, 2006) consists in designing a refractive index in a way to guide geometrical rays at will, in particular, avoiding a chosen domain thus making it invisible.”
• Planar Photonics with Metasurfaces (2013, positive): “These synthetic structures offer the distinct potential to guide and control the flow of electromagnetic energy in an engineered optical space (2) and open the door to a number of applications that were previously considered impossible (4).”
