Progress towards omnidirectional transformation optics with lenses

By Johannes Courtial, Stephen Oxburgh, Euan N. Cowie, Gregory Chaplain, Jakub Belin, Gavin Macauley, Christopher D. White and Tomáš Tyc


We study, theoretically, omni-directional Euclidean transformation-optics (TO) devices comprising planar, light-ray-direction changing, imaging, interfaces. We initially studied such devices in the case when the interfaces are homogeneous, showing that very general transformations between physical and electromagnetic space are possible. We are now studying the case of inhomogeneous interfaces. This case is more complex to analyse, but the inhomogeneous interfaces include ideal thin lenses, which gives rise to the hope that it might be possible to construct practical omni-directional TO devices from lenses alone. Here we report on our progress in this direction
